hi XDA
I am having some strange behaviour with my USB OTG...
- charges OK
- connect USB OTG cable: phone says "USB host cable connected"
- connect a memory card reader: nothing (used to work previously though)
- connect a mouse: nothing (used to work previously though)
- plug into official Samsung car dock: car dock enabled, but only one stereo channel working (right channel)
- plug into PC: Windows says "unrecognized device"
..... SO
I was thinking: something wrong with my hardware
so I ordered a new USB hardware module on ebay
and I successfully fitted it
...however
...still no change ???
looks like it wasnt a hardware problem after all
USB debugging on or off: no difference
Anyone got the same or similar issues? OTG is a really useful feature for me so I hope I can fix this
Try plugging the card reader or whatever into the OTG cable, then plugging the other end of the OTG cable into the SGS2. That seems to give a much more reliable connection in my experience.

It is not the first time I am trying OTG. This summer I was travelling and posted >100 pictures to my blog. The correct order was: cable first, then memory card reader WITH memory card already inserted... in desperate attempts I tried several other combinations but without luck.
Hi everyone,
and thanks in advance for any help / advice that you may have for me.
I'll start off with my question, before I unload all of my information. I simply would like to know exactly what type of USB Connection the Sony Tablet has, and therefore, what specific USB Cable I need to buy in order to connect it to my PC running Vista.
I bought a Sony Tablet and have been surprised the lack of information in regards to the USB connectivity of the device. Specifically, the exact 'cable type' required to connect the device to a PC. Everywhere I have read so far, it simply says USB Micro, or USB 2.0 micro. But when I try use the micro USB cable that I currently use with my Xperia Play phone (which works fine for PC transfer with the phone) it's doesn't work at all with the Sony Tablet. It doesn't even register on the PC when I plug the cable into the tablet. Just nothing.
Since then, I have read a lot about USB, and found that there are different types, like 'Mini USB' versus 'Micro USB'. Apparently there is also Micro USB 'A' and Micro USB 'B'. And finally, apparently there is 4 pin micro usb and 5 pin micro usb type.
hope this all makes sense, many thanks guys.

This tablet uses micro USB, I'm pretty sure the cable for your Xperia should work fine with the tablet. Perhaps you plugged it in upside down?
Thanks for the reply, I agree with your thought train. If it works with the Xperia, then surely it should work with tablet. I'll try it again after work today, and confirm. Is it actually possible to plug the cable in the wrong way around?
I'll kick myself if I did! Thanks again, cheers.

It cannot be plugged in upside down, unless you use extreme force and break it.

But yeah, this cable *should work, if it works with your Xperia Play. In principle there is only one kind of micro-USB cable (well, actually it could have either regular type A *OR micro type A connector at one end, but let's keep it simple. Mini-USB is a different kind and A and B are just connector types.
See this picture with different USB connectors:
http://en.wikipedia.org/wiki/File:Types-usb_new.svg
Your cable should have a regular USB A connector (the one on the top left) at one end and micro-USB B connector at the other end (the one on the bottom right).
Yeah, it should work; I'm using the same USB cable that I use with my Xperia Arc.
For what it's worth, I've been having issues too. Mostly windows fails to find the drivers and install them. I've talked to multiple Sony reps and have tried multiple computers but haven't had any luck. Maybe it's a bad cable but I have had Windows detect the device...just unable to install the plug-n-play drivers.
Systems I've tried it on:
Custom built - Windows 7 with Service Pack 1
Dell - Windows XP Service Pack 3
Sony Vaio Laptop - Windows XP Service Pack 3
I had the same problem on both of tablet P and tablet S. I can tell you, its more about luck than the wrong cable type! At the end, it just works after retrying a few plugs and unplugs.
Hope they can get a fix for this soon.
Hey again guys, I've now tried the cable again with my Sony Tablet, and I'm definitely plugging it in correctly. There's no response whatsoever on the tablet or the PC once I've plugged the cable in.
When using the same cable on my Xperia play, the phone will instantly start charging once I plug the cable in to the PC. However, the PC doesn't actually recognize the phone as a device (i.e. it doesn't show up in windows explorer, or launch the Ericsson Phone Software, as it once did). It charges the phone, but doesn't talk to it, if that makes sense.
So it would seem that some Micro USB cables are good for charging only, but not for data transfer / PC recognition.
I'll buy a different cable tomorrow so will let you know if it works then.
Thanks again for all the replies guys I appreciate it.
cheers again,
Austab
Looks like the cable is faulty then and you have to try another one.
I bet one of data wires is broken, or a data contact inside connector is broken (worn down), because when you connect your Xperia Play it should also be recognized as a device.
Then again, maybe there is something wrong with your computer.
Can you try the same cable on another computer, and see if the device is recognized, before you buy a new cable. Or let them check the cable at the store to see if it really is faulty.
My understanding is you need an OTG USB cable, (On The Go) - this is what you need to connect USB keys and other hard-drives and so therefore I would think external PCs too.
I bought a nokia one for around 5 pounds from amazon, do a search for OTG USB cables,
thanks

He wants to connect it to a computer, not connect external devices to it.
So he needs a regular micro-USB cable.
the cable is USB Host finde with this name
People, wtf are you talking?!
He *does not* need USB host (OTG) cable. That's for connecting USB devices, like keyboard, mouse, USB-storage etc., to your tablet.
He wants to connect his tablet to a computer. For that he needs a regular type A USB to type B micro-USB cable.
Hi,
Would seem like op had a charging cable, not data one. As stated, he need a regular data cable with appropriate connectors. OTG has nothing to do with it.

Hi Crazzzik,
so you're saying that there are micro usb cables for charging only, and then there are micro usb cables for data + charging etc? That would explain things perfectly for me, as my cable seems to work for charging devices, but not communicating with a PC (i.e. data transfer).
I'm getting a new cable today - sorted!
Many thanks everyone for your help & advice

Yes when I got the cable for my sony tablet s, I saw several usb cables that would fit the tablet, but on the package it said specifically "for charging only, not meant for data transfer", so they do make the cabkes just for charging, as a PC tech, I was a little embarrassed that I just found this out this weekend.
Thanks
I also got a microUSB-cable adapter, it works fine with usb driver / joypad and keyboard
but not sure if it's capable for connecting with PC or even for charging
hello all,
I recently bought the usb cable for the tablet they sell at the sony store. The micro usb to female normal usb ( I think you know what im talking about). It is sony tablet specific. The micro usb end of the cable is square instead of tappered at one side. it worked fantastic for plugging in and usb deviced to the tablet, but when I tried to plug it into my galaxy s, it wouldn't fit. just thought those thinking of buying one would appreciate the heads up so its not a shock if they try to use it on any other devices. Im sure you can find that same cable at any well stocked computer shop.
i borrowed a htc wildfire s cable, this works and installs drivers.
Hi.
I have an Xperia X10 that I gave to my husband. He's good with computers etc.. and he went ahead and unlocked and rooted this phone. It's working awesome - EXCEPT - when you plug it into the computer via USB the computer will NOT recognize it. It says exactly, " "USB Device Not Recognized
One of the USB devices attached to this computer has malfunctions, and Windows does not recognize it. For assistance in solving this problem, click this message"".
Here is a bit of background info:
Before my husband rooted the phone etc. the micro usb port on the phone wasn't working properly - it was loose and you would have to really wiggle it, bend it etc.. to make the debug engage. He did get it to flash/root/unlock/install custom rom successfully ( he installed doomkernel 2.6.29-modFXP-DooMKernel-v06) all while the phones usb wasn't working ideally. At this point he was trying out some settings and branded it as a X10i Generic. (This phone WAS a Rogers phone and we are in Canada). He then wanted to change the branding since x10i wasn't working too great. At this point the USB port on the phone wouldn't engage into debug or charge anymore so we took it to a repair place and they soldered the usb port back - they told us this was common (them coming loose). After they soldered it they said it wouldn't go into debug and that it was because (probably) of the firmware my husband put on but didn't really know.
From that day on this phone has never connected to the computer successfully - the computer won't even recognize it as a memory card - as soon as you plug it in it tries to install drivers and then the computer says exactly this::
"USB Device Not Recognized
One of the USB devices attached to this computer has malfunctions, and Windows does not recognize it. For assistance in solving this problem, click this message"
Our computer is running Windows 7 (64bit) - and the phone use to work fine.
We have tried using SDK tool, installing drivers manually when the phone is plugged in, but the computer will just say that it is already up to date, and it names the phone ' UNKNOWN DEVICE" and has the exclamation box next to it indicating it's malfunctioned. Sony software (PC Comp. etc) also will not detect the phone.
Have been trying to get this working for about 2 months now. 2 months of reading, google searches, more reading, trying idea after idea, and it doesn't work.
Has this happened to anyone else? Can someone help out here? Is this a firmware/software problem (maybe because it's been branded as a x10i)? Or could this all be a matter of the USB port being improperly fixed?
Facing same USB malfunctioned issue
I am facing the same issue since quite long since i have rooted my Samsung Galaxy 2 SGH T-989. My phone gets connected properly but when i try to transfer any of the files from computer to my phone. It gets disconnected automatically after copying the stuff till 5% to 10% and shows ''USB device has malfunctioned".
I am also trying to search and rectify this issue, but till now i have found nothing. Please let me know if you come across of kind of solution for it.
Im sometimes facing the that unrecognized USB but, everthing working.

I faced the exact same problem with my x10 mini. It wouldn't charge properly nor connect to my PC. I would have to wiggle the micro USB port and cable to get it working, which actually got me wondering if the problem was really the USB port. After I've bought a male-male USB to micro USB cable everything worked fine. Same thing happened with a brand new x10. I tried to use the USB cable I bought instead of the original one which came with the phone and you wouldn't guess, everything works fine.
So try to connect it with another USB - micro USB cable.

We have already tried connecting it to all of the (10) usb ports on our computer and we have tried NUMEROUS cables ( between my husband and I we have probably 8 cables, and have tired them all)
Hey guyz i got htc evo 3D everything runs good.but the main problem im facing is that its not recognized by my pc or any other pc.my frnd have the same phone and its is connecting without any tension but my phone doesn't appears on device manager in the same pc... i've replaced/repaired the usb port but still no good. on charger its showing charging (usb) and on pc as well.. wtf is wrong with the phone. its not in warranty . what to do .what could be the problem. help guys its urgent.
Have you tried different usb cable? Does the cable work with the other phone? Sound like something wrong with the data lines. Which should be pin 2 and 3, not sure have to check pinout.
yes i've checked everything.. even replaced the usb port. my frnd have the same phone. his phone is connecting with the same data cable and same pc but mine not..right now i have connected my data cable to pc. and on phone it is showing in disk drive mod and on notification bar it is showing a usb sign.but on pc .nothing.. what to do...
I have tried repeatedly to connect my phone to my PC (Windows 11) without any luck. Normally I would expect that just connecting the USB cable would be enough but no (I have 2 identical phones). I can connect through bluetooth and transfer files without issue. I have installed this driver as I thought being a new phone it may need a new driver still no luck. I tested the cable on my old LG phone and I can connect and transfer, I also tested the cable that came with the phone. The phone is the Chinese model with that MIUI. The phone does nothing except recharge when connected and it does not appear in windows. I have enabled USB debugging. Anyone have any idea what the problem is?
After repeating the whole exercise it appears I may have had a faulty USB A to USB C converter connected to my PC (newish case). Works sometimes, sometimes not. Using a USB A at the back of the PC now faithfully connects and solves the problem.
