The other day I plugged my x10 mini pro, (u20i) into my laptop to transfer some pictures over and the "USB Connected" flashed on and off in the notification bar, since then, the mini usb on the u20i has not worked for anything other than charging, I'm assuming it's a hardware failure but am hoping theres an easy fix for this as I now have no access to flashmode, adb, or data transfer, charging still works fine, I've tried wiping data and doing a factory reset and a complete reinstalltion of the rom but the problem persists, I'm running minicm7 2.2.0 rom using naa 11 kernel, PC companion also doesn't detect it and windows itself says that the usb device has malfunctioned and can't be detected, I'm gonna try accessing the bootloader through terminal emulator and flashing the kernel again incase something somehow got corrupted and will post the results, but I'm guessing it won't get detected anyways.
Anyone who has experienced this, or has any ideas are welcome, as without adb and flashmode I'm kinda stuck, thanks in advance.
Edit: Tried accessing flashmode (bootloader) through the terminal emulator and the phone realizes the usb is in and stays in flashmode (screen off, Green led lit) like it should but the pc still doesn't recognize it. Everything else I plug in to the pc's usb ports work so it's not the pc either.
Also I restored a backup where I know the usb was working and stil get the same results
Tried lots of different cables including the one that came with the phone, still no luck
I had something similar with my X10 Mini Pro. The USB connection would only work if I had the cable in just the right angle.
Unfortunately, it's a common issue with the design of USB ports. Repeated plugging and unplugging can lead to bits being bent. I had a company laptop that eventually only had one of the four USB ports working.
What I ended up doing with the phone was getting a very short cable (about two inches) and hanging the phone from it. I've got a tower PC and this ensured a connection every time.

my mini has a similar issue, holding the cable does the trick
for charging, i need to place the phone at the border of a table, the cable being in the air...
only way left to charge everyday

Thanks for the replies guys, I have the same problem with charging, cable needs to be at the right angle to work, but it won't work with the data connection.
again, thanks for the replies
Typed on my mimmi using naa kernel and rom
Yes, Finally got it working, after hours of fiddling,prodding and poking I finally got the pc to detect it, just had to get the cable in at the right angle, I though I'd shorted something on the main board and could never use it again, cm9 here I come

everything was fine till now with the charger,lately i have this strange charging problem which goes like this..
previously when we connect the wall/usb charger charging used to start immediately but now it takes time..i need to wait for 45 seconds then the light appears..??
previosly it used to attain 100% charge quickly..but now its slogging??i mean very slow trust me...
responds late to the power n then slow charge??????????????
its the same even when i try with usb and the worst part is it doesn even detect usb connection but charge at slow rate??
any ideas?thanks in advance!!
right now im on cobratos 2.3.4 awesome miui rom!!
So you are using APP2SDcard? You are going to have problems mounting it to USB, if the SDCard is already being used.
For the 45 second thing....I donno....do you have any Task Manager app where you can make sure you don't have like 10+ apps running? Check that. Turn all apps off and then try.

Noo im not using app2sd..the phone gets charged but not able to mount when connected thru usb????

Can you unmount the SDCard under Settings->SDCard and Phone Storage?
If you can unmount it....do that....then plug the phone into a computer (using the original USB cable that came with the phone)
And try using different USB ports or a different computer.
It not charging for 45 seconds after you plug it in would make me want to reflash and start from scratch again. Not a good sign.
That is probably what I would suggest next.
Will try with a different computer and let you no...
apart from 45 seconds delay even the charging process has become very slow:-(
Tried even with different usb ports and computer..no luck
Phones usb socket has gone I guess

Can the computer recognize the phone in flash mode?
If so, try flashing 2.1 with flashtool to fix the problem

What about getting into xrecovery?
You could flash a different ROM with the baseband it matches.
Sent from my Atrix 4G with XDA Premium App
Yea could do that but still the problem persists
Have you tried changing the usb cable? I was convinced my usb port had gone, as it took ages to recognise the charger, and I often had to wiggle the cable where it was plugged into the phone to get it to start charging.
Then I left my cable at home and had to buy a cheap £1 blackberry charge cable from poundland to charge my phone at work - and all problems went away!
After checking the ends of both cables, it looks like the usb pins have become bent inside the small end of the usb cable (mini-usb end).
I'd doublecheck this before doing anything more drastic as it's a simple thing to overlook (well, I did!)
Yep tried with different cables too..i don't think its the problem of usb port too as there is a late recognition ..slow charging but no sd connection
So, I'm having an issue where my PC can't see my phone with PC Companion open or closed, Phone on, off, or in recovery, with 2 different cables, and with USB debugging on or off.
Does anyone have any suggestions? Or do I just have broken pins on my USB port? cause I can still charge via USB.
Also, I'm on the wrong kernel so I can't access ClockWorkMod and update the ROM
I'm using an old version of this ROM (last updated mid-October, 2011)
tl;dr: PC can't see phone when plugged in, tried common sense options, what do?
More info: I did some research and found others saying they got a message saying "Unrecognized hardware" I don't even get that, nothing happens at all when I plug it in, although the phone does charge.
I have also tried 2 different PC's (both W7) and all the USB ports on both.
I would guess that the pins are busted in your phone. There are a few people with this hardware issue from my reading of the forums so this is not uncommon.
I'm in the same spot, I haven't been able to USB connect my X10 for months. The repair guy told me it wasn't fixable, so I'm stuck with locked bootloader and xRecovery flashing only.
Sent from my X10 using XDA App
That's about what I found too. Someone said to try rubbing alcohol and a q-tip or blow in it (a-la NES style) but I doubt that will work. At least you can flash with xRecovery though, I screwed something up and can't access it anymore.

Try that.. hope it helps.
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?
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.

Hi,
Having a problem since a few weeks with my s3.
Normally i could connect wiht my phone to any pc,, without any problems. Either it be unix, win, whatever...
Suddnely it stopped working, only thing that happens is charging when i connect it to my pc. Different cables tested, original one, etc..
Connecting it to different pc's resulted in a no go.. so it must be phone related.
No windows pop up, or anything!!
So I figured: Let's install a new rom.
Tried ultima 15 rom, got a different CM rom now (sentinel)... all to no avail.
Is it possible that this has something to do with my radio?
rom info:
android: 4.3
baseband: CEEMG2
Anyone have an idea what to do? Even ADB push ain't working..
See your identical post
I experienced the same problem when m using the Galaxy Nexus S But it was solved by using the app from play store named SD booster... In this app m just set the value of sd card to 1024 give root access and Boom my phone is connected as normal
If this not help then i seriously recommend you to replace the charging port of the mobile through samsung outlet
Go into developer settings, some ROMs may have different ways to get into develop er setting and after you get in make sure USB debugging is enable ^.^
Sent from my SPH-L710 using XDA Premium 4 mobile app
Usb debugging is not required for phone to pc connection see basic faqs and guides .
But as OP has ruled out drivers and cable that only leaves the phone so its worth trying .
Usual replies are
Drivers
Cable
Dirty USB Ports
Not connected to main-board usb port .
I had same issue with my Galaxy SII and when i took it to service center they said mother board needs to be replaced.
So after that SII was good as new.
Got same problem here.
phone is charging over usb , but no data connection (tried different usb cables, different usb ports, different pc etc) but nothing..
also.. tried in download mode and so (after reading forums..) but without success.
then i decided to dissasemble that phone and look, what's inside that beast
cleaned usb port (inside, with contact cleaner), resoldered all pins and etc..
reassembled it back to one piece again and still, no data connection, but only charging
so, here i am, what to do next ? change the usb port on motherboard ?
(visually, everything looks right, good solder points and etc.)
Thanks, Martin

if anybody interested:
i've got it working again :victory:
basically, the problem was the hard way (crap usb data connections on motherboard)
soldered new ways for data+ and data-, and now it's back alive again...
(pictures of ways in attachment)
Martin
see you fixed it already but a note to others :
try using usb port right on the motherboard instead of the case front panel usb ports.....connecting to the front usb ports didn't work for me on some roms, but the rear one always connected so I just have a long cable running out of the back to connect my phone and it works on all roms I've used so far
Nice work hani93, i unfortunately do not dare to desolder and solder this stuff
I've noticed another thing though which is weird!!
When i tried to charge my phone via the power charger (the ac one?), when i check my battery view it still says that i'm charging via USB.
I don't think this is correct, i thought it should say AC or something and when charging via USB port on pc it should display USB?
I think this might be one of the issues that it's also not popping up on the computer.
Anyone know what is causing this or someone can confirm that when charging via power supply it should say something else then USB?
Just confirming your question when charging by PC it says (USB) and when its charging from the Mains it says (AC).
hmmm... guess it must be a hardware issue then?
Either usb port or mainboard... christ...

if nothing again.. try to clean usb port inside (where you plug usb cable), sometimes there is dust and etc. then it stops working.
also, how did you clean contacts on motherboard ? i suggest to take soldering iron with clean bit, and drag iron along the pins.
