Hey
I was wondering if anyone else had the issue of usb port no longer charging the device?
I've plugged it into my computer, and the computer mounts the touchpad into usb mode. But my device will no longer charge (with multiple plug in chargers and multipe cables).

If you're running cm10, go to settings > storage and click on the 3 squares on the upper right corner. Then click on usb computer connection and make sure the MTP box is checked.
Hope this helps. Good luck.
Thanks, but the issue isn't getting the touchpad to mount on my desktop. I'm saying it does that already. I'm saying that my touchpad won't draw a charge from the usb port any longer, but will mount on the desktop.

Right. But there's been several cases where doing what I wrote above fixes the charging problem. Why? I don't know, but it's worked for several. You can't lose anything by trying.

Are you saying you already have MTP checked ? If not do as chicle11 said and it will charge .

Ditto above. If you cannot getinto Jelly Bean then put it on the wall charger overnight and then go into Jelly Bean.-> settings -> storage -> (three dots uper right hand corner) -> USB connection -> (enable MTP).

when I plug my usb cord into my tab it pops up with MTP initialisation and my computer doesnt recognise the the tablet. also, it doesnt look like its charging either. the battery icon has a red x in it. ive tried different cables and have rebooted once.
Does anyone have any idea what I can do from here to get this thing rocking again?
thanks in advance for any help thrown my way!!!
EDIT: found my problem atleast for the red x...I assume I wasnt getting enough power off of my wall charger. Went back to the charger that my tab came with and it is a ok now. The MTP thing still has me puzzled. It seems to be fine now so I will be a happy camper!
Thanks XDA brothers and sisters!

dubugging is off...it seems to have quit showing intialising but the battery icon still has a red x in it and it doesnt seem to be charging. when I press the usb icon on the tablet it pops up saying usb connected and right under that it says MTP connected.
this battery thing is really starting to worry me...
thanks for all help I can get with this...
Your Tab is working completely and utterly normally!
MTP is the way Honeycomb works with USB-to-PC connections due to the way the storage system works in Honeycomb.
The simplest explanation (note the length!) is that instead of having "internal" storage and "external" storage (SD card), Honeycomb merges the two together so that you have one large unified storage system meaning that you have ALL of the available space for applications rather than, say, 1GB for apps but 32GB for media as an example.
MTP is the way to get round the fact that if you mount the storage as "Mass Storage" like with Gingerbread and below phones, then Honeycomb MUST un-mount the storage from the android operating system, which as you should hopefully expect, will cause ANY app reliant on this storage to crash or worse.
I appologise if you already knew all that and I misunderstood your question, but lots of people have asked the same question and I'm not convinced you even searched before asking, but I'm nice so offer explanations rather than "JFGI"
Right, that's MTP out of the way, now for the red cross:
This one is a lot simpler: the Tab requires a lot more current than a USB connector is really meant for (5A compared to ~2A) and this can overload some USB hubs. To prevent this happening, the Tab disables charging over USB from a computer (this is what the red cross means). The wall-socket that comes in the box has some circuitry that says "oh hi Mr. Tab, here's your full charge current"
There is a way round the charge-over-USB using Pershoot's kernel, I suggest you search the Android Development section for "charge over USB"

The wall charger that comes with the tablet delivers 2A. Standardized USB offers 0.5A. Most of the standard USB plugs will deliver 1A but that is "outside" of the specification. Charging the tablet with 0.5A will take around 4 times longer than with 2A, meaning a full charge would take about 15 to 20 hours. So for most people that would be useless. Although I too would be grateful for the option at least, just in case I forget my samsung charger when on vacation.

Follow this guide to enable USB charging to remove that red X
As for why its not recognizing, try installing the samsung drivers.
Yesterday I plugged my phone into my PC and went to set it to mount as mass storage but the USB connected notification wasn't there. The phone charged fine off the USB, just didn't see the PC.
I thought this may be a PC issue until going to use it on my HD Multimedia dock, phone wouldn't recognize the dock was attached. Then went and tried it in the car dock, same thing, phone charged but didn't go into cardock mode.
Also not sure if this is related but since then battery has been discharging quite quickly.
Please help.

Hi, did you use the original cable ?
I noticed that the cable from my galaxy S II didn't work with the razr droid !

This will probably solve ur problem:
Uninstall all motorola from PC
Reinstall motocast 1.29
Connect ur razr in every mode, and wait it reinstall the drivers.
Cheers
Thanks, but it's the phone that's not recognizing the usb cable is plugged in. I've tried it on three PCs and the darn thing will only charge, not give usb connection options.
Get a small paintbrush and a can of Dust-Off or other compressed-gas sprayer.
Hold the phone between your knees with the USB port up. Swirl the brush around inside the USB jack while blowing air into it at the same time.
Try it now.
Micro USB jacks have a very nasty habit of collecting pocket lint. It can prevent the cables/plugs on any device from making a solid electrical contact.
This will likely become a routine operation that you perform once a week or so.
You can buy micro-USB rubber plugs that protect a female jack from damage and dirt. You should try the usual places to find one; Amazon, DigiKey, Fry's, JameCo, etc.
If this doesn't get it, you may be looking at either replacing the jack (if you can un/solder very small things), or replacing the phone itself.
PS: If you have geeky friends who like pranks, get a high-powered magnifying glass and check for Scotch Tape on the USB jack contacts. I've done this to an obnoxious iPhone FanBoyz phone before. I confessed before his battery was completely dead...

Did anyone ever find a solution to this? I'm having the exact same issue, have tried clearing out the USB port, different cables and every port on my PC. It charges on connection but doesn't recognise that it is connected to a computer rather than a power port.
Any advice?

Stock. I'm thinking of doing a factory reset as it has been freezing a lot recently and I suspect its a software issue, but I was hoping to do a proper backup first, however I lost root a while ago when I updated to ICS . I don't know if the freezing and not recognising computer could be two sides of the same issue?
Is there anything I am missing here? I cannot for the life of me get my Prime to show up as an external storage device. Also it will not charge when connected to my PC. Charges just fine with the regular charger.
should show up as a MTP device. I wish i could have it as an external storage device, im interested in this as well. Anyone know how to do it?

Incorrect, the prime charges fine over USB, as long as it is USB 3, my laptop charges the prime just fine.
USB 2 and previous do not output the power needed to charge the prime, the prime needs at least 11.1 volts to charge, the adapter puts out 15 when connected to a USB 3 cord, but a perfect 5 volts when connected to a USB 2 cord, so your phone is fine to charge on that charger as well.
As for connecting to the computer, check out Samba network fileshare.
It works perfectly for browsing, there is even a hack to allow you to browse your root directory as well if you have root.
However natively it only connects as a media device.
Thanks for the replies!
Well that sucks big time.. transferring movies over WiFi takes for eeeeeeeeeeever. Can't believe it's not supported as external file storage. Oh well.. get my dock tomorrow. Should simplify things I hope.
I guess you can't connect the dock to a PC to transfer either?
That is correct, the dock adds no special abilities.
Use an SD card adapter, put the car in your computer and transfer that way, as fast as it can possibly get.
Does any of the custom ROM's allow the device to be recognized as a storage device? This would actually be worth it for me to unlock my boot loader.

My TF201 is recognized as media device named Transformer Prime TF201 in Windows Explorer and I can manage the memory storage without problem.
Is the right driver installed on your pc?
You can also use AirDroid (free on Play Store) to manage your files. But it's through Wi-fi.
Btw: my TF201 is rooted. I don't know if it make a difference.
I second the advice about charging. No charge when i plug to my pc (USB2), charging when plugged to my notebook (USB3)
Usb3? Sure, if you got it.

That's not true. Like pnoire stated, you can get your TF201 to be recognized as a media storage device. And also like you, when I first tried to connect my new TF201 to my pc, it wasn't even detected as plugged in. After a few tries, I figured maybe that USB port was bad as I've known it be kind of bad from time to time. So I tried a different port. This time my pc detected it as being connected but then it was listed as "Unknown device" under Device Manager. After some Googling and searching the forums, I ran across the thread about the Universal Naked Driver Beta in the development forum and it mentioning that some USB drivers for some Android devices conflicting with others. Since I had installed the Samsung USB drivers for my Samsung phone, I thought maybe that's what was causing the problem. I proceeded to uninstall the Samsung USB drivers and then retried connecting my TF201. Sure enough, my PC detected it again and proceeded automatically install the drivers it found from searching the internet and VOILA! My TF201 is now a working media storage device displaying both the internal sdcard and my microSD card I put in it.
Long story short, try uninstalling any other Android USB drivers for any other Android devices you might've installed earlier. Sometimes the only way of uninstalling the drivers is to first connect that device to your PC and uninstalling the drivers while viewing the device in Device Manager.
I'm not entirely sure how much help this will be but I had the exact same problem as the OP when I got my prime 2 months ago. I looked everywhere and found a solution although unfortunately I couldn't find the solution again after just trying to link you to it. Go to the device manager and find your prime listed as an MTP device. right click and go to properties. I'm pretty fuzzy on this so bear with me. You should have an option to select driver from a list. click that option and you'll have a ton a driver options to select. Look for the driver called something like "Universal MTP..." and install that. I was able to browse all internal storage on my prime after I did that and it would auto-connect like any other USB device once I plugged in the prime there after. Good luck!
I don't know if this will help or not, but when I tried with mine it wasn't recognized either. So after trying a couple of times I tried wiggling the usb end of the cable going into the PC and bingo it shows up as "Transformer Prime TF201" and I can transfer files no problem.
Hope this helps.

I am confused. My normal state. Do you use the cable that is the charger cable or do you need a micro USB cable.
Thanks.

The charger cable that came with the Prime.
I had this problem with MTP drivers being screwed up on my computer and several devices wouldn't work correctly.
I Google the MTP driver error I was getting on connection and in device manager and found it was due to a registry problem. If you're having that problem I can find the guide again and send it to you.

Just got the Nexus 9 a couple of days ago, charged it, but when I connected it to the computer, nothing, it's not detected at all. Tried both a Mac and Windows laptop.
I tried a different cable and it works fine with that, just not with the stock HTC cable.
What's going on here? Busted cable? I assume it's not a charge only cable, that wouldn't make much sense. Could it be that the cable doesn't like the USB3 ports?
are yo on modified kernel with fast charge enabled? if so, please disable it.

No, just stock rooted. As I said, other cables work fine, but not the stock HTC cable, so it is the cable, not the tablet or the computers/drivers, etc.
ahh I'm sorry i missed that. anyway, surely it was a faulty cable.

Just in case you haven't tried this...When connected to your computer, tap on the USB notification on your Nexus. You will then get more options, one of which is "Transfer Files".

I know. It makes no difference, the tablet simply doesn't show up. As I said above, I know how to use other cables and they work And yes, not a fan that M defaults to charging only every time and have to manually put it in MTP mode.

No luck needed, just a different 99c cable
Just to bring closure to this thread, I contacted HTC and they finally sent me a replacement charger and cable even though I only asked for the cable (not because I didn't already have a pile of USB cables around but because I was curious whether there was something wrong with the HTC cable I received with my N9 or just an incompatibility). The new cable I received works fine for both data and charging. So the cable that came in the box was bad. But to my surprise the new charger I got also works much better, it chargers faster (I have a USB dongle that I can measure the charging current with). The original charger was capable to only charge the N9 but not other devices which I found weird.
So something went really wrong with the included charger and cable. How can it be that you have both a bad charger and cable in the same box? I can see one being bad, but both? Makes me wonder what I should expect from the tablet itself ... Doesn't look like quality is top priority at HTC, no wonder the company is not doing well at all.
For some reason the provided with cable that came with my Verizon G5 is the only USB cable that seems to work with my computer for file transfers. I've tried other various USB 3.0 cables and occasionally they will work but 9/10 times my computer doesn't recognize the device like it does with the stock cable (which Im assuming is a usb 2.0 cable?) It just makes the pluggin in noise and the device doesn't show up in the windows explorer. Anyone know why? I've rules out the cables being the issue since I've tried like 3 now to the same effect. Thanks.
I just bought one of these that works perfectly:
http://www.monoprice.com/product?c_id=103&cp_id=10303&cs_id=1030319&p_id=13011&seq=1&format=2
Though my phone does keep reconnecting at first until I select File Transfer (that option doesn't seem to want to stick and it cycles through at least Charging Only and File Transfer). Not sure why it does that, but I did just confirm that it was working by copying an album over to my SD Card.

Thanks for the suggestion. I'm pretty convinced the problem isn't my cable though. It's either a setting on my computer or the G5.

Yes it is. But even if it wasn't that shouldn't prevent it from showing up on the computer as a device as far as I know.
anyone determined anything other than whats mentioned? I have this problem as well.
I bought a Logitech cable when I stupidly left my charger plugged into a hotel wall and it works perfectly. I wouldn't rule out there being a problem with the cable itself - I've seen people say some their droid charges slower with a third party cable so there clearly are some differences.
