when I connect the USB cable onto the computer the USB notification fails to appear and the charge indicator doesnt work. The USB cable works as I had just unlocked the bootloader but now the USB does not work and I cannot charge!
Anyone ever come across this problem? RSD still detects though so I guess there may be hope

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)
I have a P769 Tmobile running V20H
When I plug into a USB 2.0 port, the phone trickle charges, usb connects, etc, everything is fine. When I plug into one of my USB 3.0 ports however the phone just charges and doesn't connect. I want to be able to connect to a USB 3.0 port. I remember it did once, but I believe that was on an older ROM. Other phones connect to the USB 3.0 perfectly fine, so I don't think it's the PC's problem.
Does anyone know the solution to this?
Hello all,
Honor 7,
PLK-UL00
B341 and EMUI 4.0
Android 6.0
Im unable to use my phone as USB Mass storage device. When i connect my phone to PC sometimes im getting as USB device not recognized and sometimes im not. I tried different PCs and different cables. ITs ONLY CHARGING
tried cleaning the micro usb port, uninstalling and reinstalling drivers in Pcs but it didnt work.
I switched off my phone, removed mem card, reinserted it, swithced it on again, connected my phone to PC(in sleep mode)
phone is detected as storage device and got notification in notification panel to select as charge only/files mode/ photos mode.
After ejecting and removing cable again back to issue. No detection. OTG also not detected. No Data transfers are being made but its only charging( even through Car USB port)
Anybody facing USB not recognised problem ? i hope its software related.
could anyone let me know of solution.
Thanks.
I am also facing the same issue
I thought I was alone in this issue.
Basically, my problem is, the wall charging and USB connect are reversed. i.e., I connect my wall charger, its showing as USB mode and when I connect the cable to a PC, its showing as AC Charging. I tested with Ampere app and when I connect to AC Charger, it is drawing only around 300mA(like it would do if connected to USB) and its drawing around 1.5A(like it would do when connected to wall charger) when connected to USB PC.
I have been having this issue for quite sometime and recently, I had upgraded to Marshmallow through OTA upgrade. I thought atleast this upgrade would fix this issue but I am still facing the same issue. I even contacted the customer care and nothing useful advice other than restoring to factory settings was suggested(which I tried and didn't work).
I guess it should be some software issue but don't know what it is or how to fix it. Any inputs would be welcome.
When I plug my phone into the PC the LED for charging lights up but I get no indaction on phone nor pc that its connected.Not even windows sound when I unplug/plug the usb.I tried to plug my mouse via spare OTG cable and it didn't work
Tried 2 spare usb cable still the same.I've also tried factory reset
EDIT: Phone model is 6037y alcatel
It say unknown device when i plug the device in
What i tried:
- Reinstall adb and lg driver, try 3 version of lg driver (4.5, 4.1, 4.4), pretty sure i work fine because i can connect with my G7
- Try plug in another port, and i notice if i plug it to my USB Root Hub (3.0), it not get recognized, but if i plug it to a Generic USB 2.0 Hub, nothing happened, it only charging (no error appear and no device appear) - I used usbtreeview to see it
- Tried with different cable, and i bought new 2.0 cable, but it still not work
- Tried buy a 2.0 USB Hub, but it get the same error as i say above, the device just charging, nothing happen, no sound of new device plug or anything appear in device manager
- Tried change the mode of usb config to MTP, PTP , then connect each mode with usb 2.0, usb 3.0 port, same problems
your V30's usb port might be going bad.
try and see if cleaning it with a wooden toothpick helps. Don't use anything metallic or conducting

I will try it! Also do you know why it throw error at when connect to usb 3.0 port of pc but nothing happen with usb 2.0 port ? (just charging),
also when try some cord, i notice that if i use my lg g7 cable and samsung cordand charge directly, it not even charge, but if i use that cord and plug to pc, it does charge ._. , and if i use my oneplus 8 cord, it work for both charge directly and plug to pc, which is really weird since all of them is usb 2.0 cord i think
