Hi, my phone just charges when I connect to any PC, it doesn't detect it on the system and even on the phone. I tried to check and uncheck the usb debugging and the logo came back on the phone (but still nothing in the PC). And now whenever i plug it in the usb debug mode comes and when I try to use mass storage option it allows but PC dosnt respond in a matter of seconds it goes away. My friend had flashed my phone with the stock rom 4.2.1 from XDA itself last year sometime in november and after that it has been great. I believed it was a cable fault so I showed it to a repair shop where the guys checkd with their PC and a new cable and none of their PCs detected it, even the OTG cable they tried wasn't detected on the phone. They say its an error in the Jack which can be repaired in a couple of hours for Rs 250. I have no problem in doing that but I don't know if its a jack error or something inside my phone (some sort of setting) causing it. Please help

Ok.
So at some point I soft bricked my phone and I got the Phone -- ! -- Computer screen.
Managed to get it back into download mode, and then unbricked it by getting it flashed to EB01 as instructed in this thread
http://forum.xda-developers.com/showthread.php?t=1026746
So now I have EB01, which is working, however there is a new problem.
When I try to plug the phone into a computer, it is not recognized (Says the device has malfunctioned).
I have tried 3 different computers. I made sure I used the cable that came with the phone.
I brought it into the Verizon store, and they were unable to get any of their computers to recognize the phone either (we tried a few other cables there as well)
This is both in download mode and within the OS itself.
They told me to try downloading Vcast however that didn't work either.
So now I'm wondering if there is something I can do to get it to recognize it properly again.
Has anyone run into this situation before and managed to fix it?
I did twice have the phone plugged in via usb to my car, and walked out the car (was talking on the phone), and the USB yanked out, so that could have potentially damaged it (though it still charges, so I don't know)
Yanking it out could have very well done it. Only thing I would suggest is reformatting the drivers and attempting again this time leaving it plugged in and rebooting the computer. If that doesn't work, replacement time.
Do you have "usb debugging" turned on?
Did you activate the connection from the phone after connecting to computer? (mine shows a green screen with a button to activate the connection for mass storage)
beyond that... idk.
redownload the samsung drivers
based on the fact that so many PC's have been unable to connect and the info on yanking the USB charger in the car (I think we have all likely done that - though for me it has happened at work with the laptop<->network cable...) you may have damaged the plug/receptor (not sure what would be proper...).
I would do a visual inspection for kicks, though I am sure there could be damage you cannot see.
I believe that these USB connections are a minimum of 4 conductors (some devices are more proprietary and use more pins to ensure you are using an official cable so they can get you to buy more of their stuff - though some of those pins are not actually wired through the cable, but rather short to each other...). If you damaged only one, that could likely be the reason that you can get a charge but no data comm - and since it seems likely that one of the two data pins would be tx and the other rx, then I could see why teh PC would report the device had malfunctioned...
I am guessing here - logic, please don't fail me...
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.
Sent from my X10 using xda app-developers app
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'm asking for a solution to get my phone to charge via PC when phone is on. I've been troubleshooting this for days. I have a Sony Zperia Z Ultra, so the battery cannot be removed. This is what I've determined:
Phone charges when OFF and connected to PC.
Phone charges when plugged into wall.
Phone shows USB debugging is active when plugged into PC.
-If USB debugging is disabled, phone will not show any indication of being plugged in.
Phone's battery status is "not charging" when plugged into PC.
PC shows phone in device manager.
-Device manager shows yellow triangle next to phone name regardless of the PC I use (all of which previously worked fine).
-Have tried uninstalling and reinstalling drivers but all PC refuse to recognize the Sony drivers for some reason. I'm also at a loss on how to get the drivers installed properly, or how they got messed up in the first place. This happens for all PCs however. But regardless of drivers, the phone should still be able to charge once plugged in. It does not.
-If USB debugging is disabled, phone will not show up in device manager.
PC makes USB connection sound/notification when plugged in.
-If USB debugging is disabled, PC will make no sound/notification when plugged in.
PC will NOT show phone in Explorer (SD Card does not show up, nor can you navigate phone directories).
Have tried 3 different computers and laptops.
Have tried 4 different USB cables, both third-party and branded.
Have uninstalled recently installed programs (from both PC and phone).
Have tried resetting, rebooting, and hard rebooting phone.
Have tried cleaning the mini-USB port on the phone, it's nice and shiny.
Have used phone for about 6 months, problem just started happening about 2 days ago for no apparent reason, no changes were made on PCs (tried several) and especially not the phone itself.
Any ideas? I can only assume it's a phone issue from using above factors to narrow it down, however which phone factor should I focus on?
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.
Issue number 1 - There is no supplied USB cable provided, only a type C to a type C cable for charging. Therefore you are unable to connect it to a computer.
I of course have a spare Type C to USB cable as my other phone (Huawei Mate 20X) came with one. Here is where the problem starts.
When connecting my phone to my computer, I keep getting the following notification:
'' USB device auto-detection stopped. USB device auto-detection has stopped because of a malfunction detected in the USB port. To connect the devices, ensure the port is completely dry or the USB device is not damaged, and tap here.
This is the first problem. Unable to connect to a computer.
Issue number 2:
I am unable to update to the latest software. I've tried wi-fi as per usual and even mobile data and for the past 3 days it says downloading.......
The update is just over 300mb and should not take 3+ days to finish. I've cancelled it and tried again several times, it never starts...
even after stopping the update, clearing cache/data from settings and restarting. Same issue. Xperia system update downloading for many days and not even started.
The phone is brand new, 2 days old, purchased from o2 and has never been in contact with any water yet I am having the above issues.
Any ideas or return it???
Issue 1 - Intended, it's a usb C to USB C cable for use with the stock PD charger. As for not being able to connect it to the PC, try using another cable. If you get the same problem, could be an issue with the phone.
Issue 2: Try updating using Xperia companion (you need to connect your phone to the PC for this)
I have usb 2.0 to usb-c cable from my previous xperia and can connect the phone try to buy such a cable.
Yeah as above, it's your cable thats the issue, and as for the update issue, go to the Sony Xperia 1 support/update page, enter your IMEI number, and if it says, the update isn't needed, then that's the way it is.
I've seen o2 pull an update before, due to their tinkering, it shows up, but you can't download it, as it's problematic.
It'll come round again, soon enough.
The latest so far on o2 is software version 55.0.A.2.205
