Hi,
Someone stepped on my USB cable when it was charging and bent/broke the USB end of the cable (not the end connected directly to my prime), the wires are loose and i'm trying to solder the wires to another USB cable that was lying around.
However i have not succeeded in making this work, probably because im connecting the cables wrong.
Can anyone tell me which wires are supposed to connect to what colours of the usb cable? They're 5 wires in a ASUS USB cable, but 4 in a regular USB cable and not all colours are the same...
Thank you!
Well the Asus cable is a USB 3.0 I believe since it uses up to 15 volts, which means you need another USB 3.0 end to connect to. Other than that I am unsure about the matching of the wires.

hey!
i got myself a used TG01 but it didnt came with a usb host cable, so i decided to use a gender changer and the data cable to connect the peripherals to my phone, but it did not work...it does not recognize anything, am i doing something wrong ? or cant it be connected with anything else then the usb host cable provided?
thanks!!

it's a generic micro USB cable, you can find it at NOkia or HTC store
thanks for the reply, i already made some research and found out that the host cable is in fact a special cable that has 2 wires grounded on the micro usb side.
i actually was able to make one, but it must have broke a soldering point and if i connect it, it drains my battery in 10 minutes...
after the failure i just brought one out of ebay.
regards!
BTW: i encountered and other problem...
i had 2 micro USB cables, and i destroyed 1 to make the host cable, they looked the same so i picked one at random, now the phone wont change with this cable with the ac adapter connected i have to connect it to the PC to that it can receive power.
I tested with an other cable and it worked...has anyone experienced this?
I made one using an old USB extension cable. It took about 10 mins. Short the green and white wires on the female side of the USB cable. Now will use any normal in-car charger.

you have to have a short on the 2 data wires for it to charge.
I remember someone from this forum or elsewhere, told me that all I need is
a connector of USB3.0 female to female.
When I arrive Shanghai few days ago. I began to search for such connector.
There're only three seller on taobao. Only of them got stock. So I order the
connector and USB3.0 extension cable(Male to female)
Here's the result:
USB3.0 extension cable can use to connect between original adapter and
USB sync cable. Then you got 1.5m~1.8m longer of cable for charging or
connecting to PC.
The USB3.0 female to female connector didn't work in anyway. No matter
I try USB mouse or USB flash. It just won't work. Maybe Asus design
some tricky stuff about the OTG function.
Anyone got better luck?
I've tested it like you, without any success.
I've bought a dock... and soon the USB connector.
I tried with a USB sync cable I got of ebay. It did not work bit not I read this thread and see there is a needed 4th wire.

I will try it in the morning.. Bit late here now.
Is there any way to connect a USB Host adapter + charge the TF at the same time? I'd like to be able to watch videos (most of which are on my USB HDD) without having to spend hours copying them all to MicroSD just so I can charge the TF (and I use it a lot in my car (while parked, not while driving obviously) and dont want to have to dock the TF to do so (the main reason I use a tablet in the car is there is so little space between me and the steering wheel))
Possibly dissecting a Datacable so it forks the charge into 1 plug and the USB into the other? or wiring in a barrel plug to one of the USB host adapters? (I'm assuming it's not possible to just use a generic USB hub and somehow reverse the power on one of the ports to allow charging...?)
Not sure if his answers your question, but essentially, the pin layout on the cable that connects to the wall charger for the Asus Transformer matches the USB 3.0 spec.
As seen here on Amazon, you'll need a USB 3.0 cable to effectively work as an extension cable for charging via the wall-outlet.
Therefore, by the same logic, if you have a USB 3.0 port on your computer, you'll be able to make use of the extra voltage to do the same thing.

I don't think the USB 3.0 on a computer will supply more than 5V and 900mA. Not enough to charger the TF.
You best bet is to use a USB 2.0 extension cord, take out the wires that go to pin 1 and pin 4 and connect those wires to a 12V power source.
Absolutely no need to use a USB 3.0 extension cord.
Look here: http://forum.xda-developers.com/showthread.php?t=1087321
To answer OP's question, there's only 1 USB host port on the ASUS Transformer TF101 USB Kit. I don't think that's possible.
Confirm both replies - the Amazon-linked cable does indeed allow an extension of the power delivery from a stock power adapter, but connecting to USB 3.0 port on a PC will not charge the device. Just connected it direct too, not via a hub (even though it is a 3.0 hub - didn't work on that either...)
Suspect custom wiring required, as OP has speculated - anyone?
Can EEE PAD Transformer support Full USB HOST functionality using stock connector provided by ASUS using something like below FEMALE TO FEMALE USB Adaptor ?
http://www.hkcolordigital.com/usb-2.0-a-female-to-usb-2.0-a-female-adapter.html
I know ASUS dock keyboard do have USB port and also, ASUS is selling USB adaptor for around $45, but I do not want to spend that much.
Since ASUS stock connector which is used for charging as well as data transfer from PC support USB functionality, I believe it should be easy to implement.
Any suggestion/solution ?
Thanks
No, it wouldn't work.

I can't find pinout for ASUS charging connector, but i think it has USB-host pins in it - so you should just solder an USB-female to them in right order.

this might work. USB OTG is what we looking for
USB Adapter Coupler Type A Female to Female
I have ordered "USB Adapter Coupler Type A Female to Female" from ebay ($3 including shipping):
http://www.ebay.in/itm/120868617077?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649#ht_932wt_1143
Once it reaches to me, I'll try what is possible with it.
I received the "USB Adapter Coupler Type A Female to Female" today and tried to connect USB pen drive and as it was expected, NOTHING HAPPENED.
But, I still think it is possible. I have seen Nexus and Galaxy phones with USB host online.
I think, to be precise, it is not only Female to Female adaptor to be connected to stock connector, but it needs some power (+5v) as well. For this, I think it need USB Y Connector, as in attachment. Below is the link for reference:
http://htc-linux.org/wiki/index.php?title=Msm_Usb_Host
Now, I am thinking to open Female to Female USB connector and solder 2-wire with USB Male connector to it (I have extra USB mouse) for power (+5V & Ground) and try again.
look at last link in my previous reply. There are photos of disassembled host adapter and some schematics-pinouts. TF has USBhost, but it on different pins than usb-slave cable.
Has anyone made an OTG cable for the TFP? I don't like the chunky USB OTG connector and thought an OTG cable would be much better.
Not quite sure what you mean.
The only proper usb connector is a standard type A connector located on the keyboard, it has insufficient pins to implement OTG. The only other usb connectors are the propriety asus ones, one on the tablet and one on the keyboard, the other small connector on the tablet is HDMI output
I have the "chunky" USB OTG connector as well.. I don't think there's a cable though... I looked everywhere on the net
I don't have a dock therefore the only way I can plug a USB flash drive, Keyboard/mouse into the TFT is via the ASUS USB OTG Host adapter View attachment 1384503
I was after something a little slimmer and believe a OTG cable would be ideal - Refer to picture for an example of what I'm referring to View attachment 1384504
Micro USB OTG cables can be used with many phones and tablets sporting a micro USB connector. The TFP obviously doesn't have a micro USB connector therefore I was hoping someone knew how to make an ASUS 40 pin to female Type-A plug which replicates the ASUS USB OTG Host adapter.
Has anyone pulled apart the ASUS USB OTG host apapter? What's inside it?
Hey guys. There are several articles and videos around on how to make your own OTG cable. It essentially involves shorting a single pin. I have no idea if it'll work with a TFP, but I'm going to give it a shot today or tomorrow if I get some time. My plan is to use the normal TFP USB cable, but plug it into a female/female USB gender changer that has been modified to short the pin. I'm almost positive that it'll work on my SGS3, and I don't see why it wouldn't also work for my TFP. I'll report back.
Nevermind. I now see that the TFP USB end has five pins, so they won't match up with the 4-pin female USB port. Oh well...
TFP and OTG
Does anyone know if the OTG will support a USB hub?

The TFP doesn't have OTG, it's a regular USB host.
So yea, it will support a hub because it's a standard USB device class, with its driver already part of the kernel.
