So why I can still charge my phone like usual?
Does it make sense that I can charge my phone but can't connect it to my PC and transfer data?

Yes, because the USB connector has specific pins for data and power.
The old USB 2.0 and below used 4 pins, which were +5v, Data+, Data-, and Ground. USB-C uses 24 pins - 4 ground pins, 4 power pins, 12 data pins, etc.
A USB A to C cable has the GND pin on the A connector connected to all 4 of the GND pins on the C connector, and the VBUS pin on the A connector connected to all 4 of the VBUS pins on the C connector, but the two Data pins are only connected to the two USB 2.0 data pins (A6 and A7) on the C connector.
So, if the Data pins don't make good contact, but the VBUS and GND pins do, the phone will charge...albeit at the slow 5 volt rate. I assume when you plug it into the charger, it doesn't charge rapidly?
Make sure there isn't lint or dirt buildup in the USB port of your phone. Use a small thin plastic pick to gently scrape out any crud that might be in there around the connector. Don't use any harsh chemicals or solvents; you can use a small amount of isopropyl alcohol to help clean if necessary.

I see, thank you for the deeper explanation.
Although, I found a bypass solution which I don't understand how it works:
I took a UGREEN hub that I bought from Aliexpress a few years ago, I plugged the Type C connector to my S21, I took a 128GB Flash Drive and connected it into the HUB and guess what? it worked! so I managed to backup files from my S21 to my USB Drive via the HUB I put between them.
I still don't understand how it worked and why it doesn't with a direct connection of my phone to my Laptop..
The cables are great and Samsung original ones.
Also, 1 of the 2 cables is new, I bought it a month ago.

Did you use the right firmware?
If you've already cleaned the USB port the only thing I could suggest at this point is doing a factory reset and flashing the firmware again, being careful to make sure it's the right one.

Can i use a regular mini USB to update my G!?

Hi I lost my G1 cable and I wanted to know if I could use a regular mini USB to update my G1 without having issues?
Yes, you can.
Make sure the miniusb cable you are using has a ferrite core/bead on it. Some folks with poorly shielded computer innards have experienced data corruption on cables without ferrites. If your miniusb cable doesn't have one, look around the house for a computer cable with a core that you can remove.

You can remove those things? I thought they were attached to the wire. I've just been using random junky usb cables with no beads on 'em and I haven't had any problems. I just checked the cord that came with the G1 and that doesn't even have a bead on it.
yeah hes saying, some people, so more often than not you dont need one, its for people who like to be extra safe especially if they end up bricking the device from corrupted data.
one thing that i have heard is that adb will not work if you are using a regular cable, there are a few extra wires and connectors in the usb cable for the G1, it is also a different shape than that of a regular mini usb connector. but for daily use, or just moviing files you shouldn't have any problems
Err, I have several mini USB's, I usually randomly grab one when I work with my G1, I have never had a problem with using ABD or any other type of problem. Also, I'm 99% positive the stock USB cable is no different then any other cable.

and i am 100% positive it is different from 99% of other mini USB cables. look at the input for the cable on your g1 and compare it to the mini USB port on anything else you have laying around your house and you will notice there is a difference

Yes, The input is strange, The HTC Shadow is the exact same way. Do realize, the stock USB's "Head", the metal pin, is not the perfect match for the slot on the Dream, it's a basic mini USB. Although, The included stock headphone/ear piece's connector, does in fact fit the input in the exact manor.
I think it's just the "head shape" that is different. I hvn't had any problems with other USBs.
Yes, currently I am using a Blackberry USB cable, and ADB and all functions work properly. In the past, I've used the original G1 cable, one for a Canon digital camera and one for an HTC Vogue, ADB works for all of them. Most of all, USB stands for Universal Serial Bus.. so I assume they are all the same.

It's an ExtUSB port, which is a HTC variant of the mini usb plug that has additional pins for audio. However the usb data lines are physically and electrically identical to standard usb, so for all intents and purposes unless you are using a special ExtUSB headset, it is plain mini usb. The supplied cable is a standard mini usb, so any other mini usb cable will work. Do heed my earlier warning to use a cable with a ferrite though.
I have about 30 different mini usb cables sitting around the house and i have probably used all of them once to or twice well doing playing with my HTC devices
Actually, that ferrite theory might explain things for me... I am experiencing some strange behavior when I use cables without the ferrite bead - the G1 will act as it's charging, but I don't get the "mount" option, i.e. it doesn't detect that it's actually connected to my computer. This happens both when directly connected to the computer USB port, and via a USB hub. I'm pretty sure that when I use a cable with the ferrite bead it also detects the computer and I'm able to data mount it.
Also, when using a cable without the bead, I have noticed that although the G1 says it's charging, it either doesn't or it charges really, really slowly, cause I could check by pressing power or menu once that it says charging - 76%, then turn off the display, then check again like half an hour later and it's still at 76%.
So I would actually say yes: the USB cable matters big time.
But of course, this is all based on my personal experience.

i plugged up an old desktop to retrieve some stuff the other day and realized that it didn't have usb2.0 and would not let the phone stay mounted. so just a caution if thats an issue.

strange, that's a similar thing that happens when not using enough voltage (the battery issue). I have a homemade battery powered usb charger, but it's only 4.5v as opposed to 5v. This causes strange issues with my g1 and my girlfriends. do you have lots of things drawing power (LED lights, lit up SATA cables, tons of usb stuff etc) because that can cause instability with your computer and sometimes undervolting usb things.
Ferrite beads more have to do with interference which doesnt seem like issue. Although i'd certainly use a cable with a ferrite bead when flashing or issuing commands via adb, flashboot etc.

I use that and no problem occurred.HTC cable have 2 side for connection and send or receive or power supply,but usb 2 mini have one side only.
can I use this cable without problem and damaging device?
Yes -- I've been doing that for years.
If the plug end physically fits, it will work fine. I've tried a couple mini USB cables that didn't fit, due to the way the HTC Ext-USB port is shaped straight on one side, like you mentioned.
CORRECTION: I think I just wasn't pushing the connector in hard enough. I have a couple mini-USB cables that came with various devices (a multi-card reader and a digital camera), and they take a little more effort to push the connector into the port on the phone. I didn't realize this at first, since I was afraid to damage the pins in the port. But they fit fine (just take a bit more effort than the OEM cable), and both transmit data and charge the phone properly.
I connect usb2 Cable and trasnfered data successfully.
but when I try to charge with usb 2 cable,device dont charge and only charge led be turn on.any body charge with usb cable?
Charging via USB is at a much lower rate. It can take 3-5 times longer to charge the phone that way.
I've only ever used the USB2 to transfer data/charge my phone since I had my Wing which was a good 3-4 years ago lol.
Hello everybody,
i have tried to use the mini usb with my TP2 and only works for charging.
when conect it to pc, it just start to charging, i have installed active sync but pc doest detect device,
Any advice?

Go to Settings>System>Power, and make sure the option is unchecked: "When phone is on, do not charge when connected to PC".
Ok, tank you redpoint73, i have unchecked this option.
i just ordered the original data cable, which is supposed to have 11 pins,
I dont see how a standard mini usb with 4 pins can do the job of the 11 pins
Any USB-mini cable should work for data transfer and charging. There should have been one included with your phone, and it should have come with a wall charger as well.
There are retractable cables you can use. I purchased several from here:
http://www.itrimming.com/pcabusbx0007.html
They are a little delicate though. If you're rough with it, the end of the cable closest to the plug will fray. The site also has some great universal USB car chargers.

If you had to install Active Sync I assume your on Windows XP. Make sure you have installed the htc drivers.

It doesn't do the same job, the extra pins are for composite video output, left, right and ground for audio, microphone, and possibly FM antenna. Four pins of the standard USB cable are all that is required for data transfer, even though it (USB) has five pins on the phone end.
You may have, as I did a failed USB interface. Check the phone on another computer to be sure it is not an issue with the computer and/or its software. All you have to do is verify the computer senses the phone, you don't need to sync them.
Two quick things...
I have one USB cable for a card reader that does not work for WMDC/disk mode, but charges the phone just fine. It works with the card reader OK, but no data on the phone basically. If you have problems with one cable, unless it is known to work on other WinMo/HTC devices, I'd definitely not always assume the phone is at fault until you've tried a different lead.
I've heard a lot of people say that charging via USB is a lot slower than via an AC mains charger. However, using SpoonCharge, the mA figures look the same for me on my phone - charging via mains charger never goes above "medium". This holds true with the original AC charger my UK (new, sealed and boxed) TP2 came with, as well as a TyTn II, Hurricane and Typhoon charger, and a non-HTC MP4 player charger - nothing goes above medium.

I have measured the current used to charge.
There are a few things.
1) Most PC USB ports are limited to 500ma., that is the standard. Try to pull more, and they usually do an auto shutdown or some form of limiting.
2) Any plain USB cable, or the factory HTC cable when on a PC port, leaves a charge rate pin floating. With that pin floating, the HTC device charges at a max of 500ma. Again, this is by design to not overload the PC port.
3) The factory charger, pulls one of the extra USB pins down. That tells the device that it can charge at up to 1000ma., twice as fast.
4) So, if you plug into an official charger versus a USB port, the charge rate is about double. BUT, you need to factor in the processor activity. If the PC USB is keeping the phone active, then the charge will take even longer.
I use my HTC on my motorcycle as a GPS. I have built a charger on the motorcycle and have used a switch in that 'fast charge' control line to lower the charge rate, or raise the charge rate. (long story, the phone and my regulator gets hot).
I have a pinout somewhere. A Google serach will find it.

[GUIDE][DIY] Charge-while-syncing cable ("Benchmark" added)

This guide is based on [GUIDE] The $6 way to charging your EEE Pad on your computer, taken one step further.
DISCLAIMER! YOU DO THIS ON YOUR OWN RISK! IF YOU SCREW SOMETHING UP ITS NOT MY FAULT!
This guide will show you how you can charge your TF101 from the PC, while also have it connected through USB allowing you to sync etc just as you normally would.
Its possible this method also works on the TF201, but I dont know for sure.
Difficulty: Pisseasy
Parts and tools needed:
A female molex connector with the yellow(+12v) and black(ground) wire. Where you get it from doesnt matter. I stole mine from an old pci-e -> molex adapter.
Headphone extension cord (or any other 2-wire cable you can use as a connector)
USB extension cord (2.0 works fine, no need to get a 3.0)
Tape (or if youre not as lazy as me - a soldering iron)
Teeth (or a wire-stripper/cutter)
Carpet knife or similar
Multimeter, not necessary but recommended to check if the power is correct before hooking it up to your tablet.
Ok, lets get started!
Id like to apologize for the rather vague images. I took them after I had actually built the cable.
Grab the male end of the headphone extension cord and cut it, leaving a bit of cable (I left around 20cm)

}
Next, grab the USB Extension cord.
I wish I had a better picture for this, but its not that tricky. What you want to do is remove the cover around the shielding, remove the shielding and exposing the 4 wires.
Once thats done, cut the red and black wires, leave the green and white.
Strip the red and black wires going towards the female end of the extension cord.
Connect the white and red wire from the male audio extension cord to the red and black wire on the usb extension cord. I suggest you attach red to red, white to black. It doesnt matter much though, but do remember how you connect them.
If done correctly you should end up with something similar as the picture.
Grab your favorite roll of tape and secure the wires and you should end up with this
Gratz, the first part is complete! Now to steal some power from the PC.
Grab the remaining part of the audio extension cord, which should contain the female connection.
Grab your molex connector (In the picture, I have already stolen one of the molex connectors)
Now, strip the yellow and black wire on the molex connector, and strip the red and white cable on the female audio cord.
Connect them the same way you did with the usb cable (if you followed my example, yellow goes to red, black goes to white).
Excuse my extremely dusty PC... Im ashamed :x
this might be a good part to route the molex-female audio cable inside the PC so it reaches outside.
Once thats done, simply hook the molex connector up to a free connector in your PC
And finally, grab your usb-male audio cable, connect the male audio with the female audio and plug the usb end into a free usb port.
Finally! Hook up your original TF101 usb cable to the female end of the USB cord and enjoy being able to charge your tablet while transfering files!
WARNING! Do NOT connect anything but the TF to this cable. 12v will fry any normal USB device.
Troubleshooting:
If your tablet does not react when you connect it, you have most likely gotten the polarities wrong. Simply switch the place of either red/black on the usb cable, or yellow/black on the molex connector (this is where a multimeter is handy).
There are many ways of doing this, I chose to do it like this because I had an audio extension cord lying around, and I wanted to be able to detach the cable from the PC.
Basically all you have to do is cut the red and black wire from the usb cable, and hook them up to the 12v rail on your PC instead of the 5v rail USB is running on.
How you chose to do this is, in the end, up to you.
Additionally, if you replace the audio jacks with some other more standard DC plug, you could use this cable to charge your TF using any DC adapter that provides 12-15V.
Once I get a USB Extension Kit for my TF, Im going to try to add a charging port to that as well. If I succeed in that, Ill post another guide covering that.
If you found this guide useful, hit 'thanks'
I'll try it when I'll have the time =) Nice tutorial!

Son of a.... Youre right... Ill fix it...
edit: Pictures should work now.
Heres a "benchmark", or whatever you want to call it, showing roughly how fast the tablet charges.
Note that the screen was turned on all the time, and I used it occasionally.
It does indeed charge slower than the real wall-charger, but thats not strange considering theres a 3V difference.
The wall charger charges an equal amount in roughly 1:30h, during the same usage.
Edit: I forgot to mention, if you use this method you can extend the charging cable easily by just hooking up an addition audio extension cable
Do beware of voltage drops though, the cables aint exactly thick. My cable is around 4m total, and I get a voltage drop of ~0.5v from the molex to the female usb plug.
I tried this and got to the extention cable section, I totally butchered my usb extension cable and gave up since I don't have another. Great guide though! I just can't cut and splice without completly failing and breaking things -_-

Dont know how you managed to butcher the cable though , you just need to strip 2 wires (or 4, if you decide its easier to cut the white and green too), and wire them together.

TF101G: Charger cable broke -- need urgent alternative

Hello all,
I have the following problem: The USB connector side of the standard charger cable for my TF101G is damaged beyond repair. The wall wart is fine.
In my naivity I bought the standard USB adapter (namely this: http://www.amazon.com/Transformer-T...INXQ/ref=sr_1_6?ie=UTF8&qid=1336838294&sr=8-6 ) believing that a "standard" USB Type A male -- male cable to connect the adapter to the wall wart will do the trick.
After finding it doesn't I browsed (quickly...) this thread http://forum.xda-developers.com/showthread.php?t=1087321 . It seems that the adapter is using some different wiring...
I tried this with both USB 2.0 and USB 3.0 (male - male) cable between the wall wart and the USB adapter to no avail.
Question is simple: Can I use the adapter I bought -- via some easy modding of the USB cables if needed -- to charge the tablet (and keyboard) ? Or I simply need to buy another charger ?
Thanks,
Florian
No, the pins used for charging is not in use on the adapter.
You can quite easily fix your cable though, if the 40-pin connector is still intact. Its just 4 (ok, 5 actually) wires.
If its only part of the cable thats broken, you can just cut the cable and then cut a USB3 cable and solder them together. red to red, black to black, white to white etc... the 2nd red wire is supposed to be attached to pin7 of the usb3 cable. I dont know the color of that though.
The wall wart outputs 15 VDC @ 1.2 Amps when the TF is detected. If not, it will output the standard USB 5 VDC @ 2.0 Amps. Any voltage less than 11 VDC will not show the tablet charging.
A USB port (5 VDC @ 0.5 Amps) will charge with the screen off at a rate of 3% per hour.
An iPad charger (5 VDC @ 2.0 Amps) will charge with the screen off at a rate of 10% per hour.
If you are looking for a charger, it will have to output between 12 and 16 VDC across pin 1 and 4 of a USB connector.
You can make your own, or try to find one. Dynex makes one, or you can check some stores. ASUS sells them online, as do some other vendors. Depending on where you are located some users may be able to help you find one.
There is plenty of info on the forum on DIY chargers and such. Here is one thread:
So you can only trickle charge without ASUS charger?
or you can just build your own pc usb charger (see link in my sig)
Thats my charger just went tits up aswell. 3 days of gtee left! Tried freezer but no joy. Looks like its outputing something by the indicator on the tf itself but % still drops, dock indicator light doesnt come on.
Cables ok as pc installed drivers etc when connected.

Sounds like mine... it refuses to send 15v anymore, it only sends 5v.
Im going to rip mine apart, when I get some free time, and see if bridging the connections will help kick it into 15v mode again.

Welll...Tbh I'm not so sure I want to take the knife to an USB 3.0 cable....
If you look at the attached pics of the (damaged) connector you'll see the Red & Orange cable (still) soldered to Pin 1, the Shielding was (seemingly) connected to Pin 4, while on the other side (the "top" of the connector -- see 2nd pic) i have the Yellow Wire... well, not sure where ...Shielding ? Also, unclear where this yellow wire goes..
Anyway. My "problem" is that
1) Bought the USB adapter in vein (stupid, $45 mistake). Anyway, lesson learned.
2) I still isn't clear to me on what wire has to go where on the USB 3.0 side and I don't really want to take risks in frying any part (the tablet or the wall wart...)
Thanks anyway. Still looking for alternatives / safe way to reconnect this...

Not to throw a wrench in the works here, but I have a cable that installs drivers and functions just fine when connected to computer, but will not charge from either of the two wall adapters I own. Another cable I have will work with both adapters.

I bought one of these 2m cables from ebay and they work fine, you may find cheaper but this one does work and its longer that the original which is a bonus.

Edit :- I also have a 3m USB3 cable which I can use as an extention to the existing cable (or the 2m one above) so I can sit quite a way from the plug socket without a problem.
Spot of luck.....Asus tf came in to my store to get sent back for repair. So my tf is now happily getting a charge from the borrowed adaptor until ups pick it up
My charger was picked up yesterday and is currently tracked to Germany. Just as a tip for anyone - rma your tf yourself! Don't take it to the retailer to do it......Asus are hopeless with the retailers and seem to think its OK just to string it along knowing the retailer will take the flack.

Spot on m8. It was the cable. Charger was returned back to me today. Really good service despite the bad rma experiences for others.
Does anyone know where you can get a us outlet snap on plug for the stock charger? I just traded for a tf101 and one of the prongs is broken..

same problem
My kids did tear my cable and I have the white, yellow and green wires to reconnect. Is your sequence right? ?I mean is yellow connected to pin 7/15 volt contact?

Welll...Tbh I'm not so sure I want to take the knife to an USB 3.0 cable....
If you look at the attached pics of the (damaged) connector you'll see the Red & Orange cable (still) soldered to Pin 1, the Shielding was (seemingly) connected to Pin 4, while on the other side (the "top" of the connector -- see 2nd pic) i have the Yellow Wire... well, not sure where ...Shielding ? Also, unclear where this yellow wire goes..

LG G2 apparently has USB 3.0

I'm not sure if this was discussed or brought up in any review/presentation i saw. I plugged my phone into my computer and i get the little windows pop-up this drive can perform faster if plugged into a 3.0 usb. I haven't tried it yet, since my 3.0s are behind my tower. Anyone notice or try this to confirm?

I've heard about this as well. But I don't see how it's possible since the G2 dosen't have a USB 3.0 Micro-B port. Compared to the Galaxy Note 3, which does.
I'm pretty sure people are seeing this message because the Snapdragon 800 chipset supports it. But the G2 does not actually have the circuitry for it.

LG's own spec only says 2.0, so I'm pretty sure people are seeing this message because the Snapdragon 800 chipset supports it. But the G2 does not actually have the circuitry for it.

you would be correct. Tested it out. Even plugging into 3.0 it still pops up that message and it still took 25 seconds for a 430meg file.
The USB port used on the LG G2 does indeed have extra pins that could be used for USB 3.0. If you look directly at the port, there is an additional 5 pins recessed behind the standard connector. As of yet I cannot figure out what they do, but they may be a proprietary connector for a custom slim USB 3.0 connection. They could also be for some other uses, such as video out or for connecting to accessories, but I don't know what.

I was wondering what all the recessed pins were there for, I assumed some future lg accessory

Here's to hoping they see more use than the Galaxy Nexus' POGO pins.
I dunno, the official spec sheet shows USB 2.0.

Look at the bottom spec area.
Pics? No idea where you guys are looking.

Yeah, the same thing popped up on my laptop 2 days ago when I plugged it in. I've been wondering about this...

I guess that it is HDMI pins
G2 is plenty fast compare to my previous Galaxy Nexus.

Slimport prob
I have tried it. First, plugged on USB 2, got error, then plugged it on USB 3 port, worked fine, no notification at all.
Haven't test if transfer speed meets USB 3 specification.

What cable you have used? On stock cable I still got an error on USB3 port.

Stock cable.
The g2 has a usb 2.0 port on the phone. It won't support the faster transfer speeds or the faster charging of usb 3.0. It doesn't have the extra pins of micro usb 3.0.

If anything it would be SlimPort, which the phone does have, but I don't believe SlimPort uses any extra pins, just the normal micro USB 5.

The chipset fully supports USB3 standard as it has an integrated controller for it. When you plug into a computer the phone even gives a notification popup that it supports USB3 for faster transfer speeds. The port appears to be a USB2 port though, and a USB3 port would look like this:

Those extra pins probably have to do with HDMI output through the USB port as ddv2005 said.

Exactly. USB 3.0 microUSB port is much wider than a USB 2.0 microUSB port. There is no way the LG G2 can support the speeds or charging of USB 3.0 with the current USB 2.0 port. That warning only comes up because the G2 contains the Snapdragon S800 chip that has USB 3.0 support.
I'm not sure you'll want or need USB 3, for the following reasons:
1. You won't want it for charging, because the faster you charge a Lithium-Ion battery, the quicker it dies. We all charge it overnight, so we have at least 5-6 hours for charging, and it needs much less.
2. You won't need it for file transfer, because most of us don't was to fuss with cables, and simply use wireless transfers. Not to mention the storage on the LG is so small (16 or 32GB), that there is simply not too much to move...
