Hi, I have reflashed my ROM I dont know how many times. Yesterday I tried to connect via activesync on a new ROM and it wouldnt connect. These are some of the things that happened:
Device orange charging light flashes a few times then goes off [never seen THAT before]
Activesyc menu comes up on device but activesync doesnt connect
Get 'this device can perform faster' message on desktop
Sometimes get USB devce not recognized on desktop
SOmetimes device orange charging light it stays on if I plug direct into PC but still doesnt activesync
I have tried to connect as DISK DRIVE but I dont see the device on my PC.
Have tried different ROMS, 6.5, 6.51, sense 2.1 and 2.5 but all have same issue. Have also tried connecting to other computers. same issue.
Have played around with USB to PC menu options (enable / diable faster data sync etc) but doesnt make a difference.
Anyone had this problems? Thoughts?
Have you tried diselecting "ask me 1st about usb connection type when I connect the device to the pc" under USB to PC settings
It worked for me
This is the exact problem I am facing!
I tried everything - as diskdrive, activesync (with/without speedup), etc.
On many ROMs, even the original one (WM6.1)
Can't connect - every PC gives an 'unknown device' and on some ROMs I cannot charge via USB, only via mains...
I also tried without the question on connection.
Just some thoughts:
Do you have corruptions on screen sometimes? (Some graphical glitches)
Any .CAB files you cannot install?
Did you try to reflash the same ROM more than once?
tried to connect without card in the device and in flight mode? (Uses less power)
With me it started after a ROM flash from Miri... (I don't blame him!!)
The Hard SPL did not give me any problem, the radio was not flashed, just the OS. But reverting did not help.
I certainly hope you will find a solution, since I have the exact same problem!!
Do you stil know what ROM you flashed when this problem occured?
I reverted to original ROM 6.1 AND 6.5 which included everything - boot, radio, os, stardup image. But it did not change!
I figured it out after trying everything i could: i think its a hardware problem. I have dropped my devicetoo many times, or plugged it in too many times. Who knows.

And how did you figured it out? Did you return the device to the shop?
I have this exact same issue except I am on AthineOS... I thought it was my PC until I read these posts. No OS updates or any other machine updates were performed except on my device. Any clues as to a fix?
Somehow I don't think this is just hardware.
I did drop my device once, but that was even before first flash. After that it still worked.
So, some weeks later I HSPLed without any problem. After that the device still worked.
Then, after investigating which ROM to use I flashed the ROM a few days later.
Right after the first flash it all still worked. So, had to flash another and from that moment on the device cannot be reckognised by any PC.
I still think it has something to do with the flashing. I think the device does not give correct feedback when it receives some commands from PC (eg. the command to reply the device type/number)
Does anyone know a program which can check the USB port for the HTC Touch Pro 2? Just to test wheather the connector pins are ok?
download activesync 4.5 and run the setup. it will perform a repair. that usually solves the problem. if not, try a different usb cable and try plugging into different ports on your pc.

These are the first things done. And this was already written in here.
It happens with many PCs, including some on which the device never connected to.
Also tried different cables, ports, etc.
Also disabled the fast transfer etc. etc.
Even tried several other ROMs, inclusding original Dutch 6.1 and Dutch 6.5
I'm having the same issue. I can connect via bluetooth, but not usb. And I'm stuck with 6.1. I was tole my phone was brand new, but now I'm starting to think otherwise.

Some questions, to verify this is due to flashing or is a fault in the design of the device...
- Where did you get the device?
- Have you flashed the device?
- Did you accidentally drop the device?
hi just to say had a completely orignal o2 xda orbit 1 flashed with new rom everything worked perfect before now active sync plays up i can sometimes connect but get usb device not reconigsed then click cross then pull out usb then reinsert then active sync connects works fully functional then after 5 min it disconects this is driving me mad as use active sync for a fast internet connection on my pda as my wifi is crap
I connected my SG2 via USB cable to my PC and started seeing this error
"One of the USB devices attached to this computer has malfunctioned and Windows does not recognize it. For assistance in solving this problem, click this message."
I have tried everything from changing cables/PCs/enabling/disabling USB debugging to *#7284#, and none of them work ...
Is the device bricked, is there any hope of revival..please help i got this phone myself paying $400
Does your phone turn on and work and a connection to PC the only problem? If so your not bricked...you prolly need to install the drivers in order for your PC to recognize it so install kies on your PC
Sent from my SGH-T989 using XDA App
Yes phone turns on, charges through the port...just that it is not recognized by the PC....what could be wrong?
As I said previously you probably need to add the drivers on your PC install kies on your PC
Sent from my SGH-T989 using XDA App
Make sure you use one of your rear usb ports also. I had an issue with drivers installing in a front usb port.
Phew it turns out to be the samsung driver..I believe kies update must have corrupted and stopped the pc from recognizing the phone....

The definition of "bricked" is having a really expensive
... brick. It means your phone doesn't turn on no matter what you do to it (short of a JIG and that's not guaranteed) the "USB device not recognized thing" is a problem w many windows devices my vista computer does it all the time and I just switch ports.

Having same/similar issue
Hey, was there every a solution found for this?
I'm having basically the same problem...using the cable that came with my phone, and have installed Kies (fresh). I have tried toggling multiple settings. I tried uninstalling kies and reinstalling. I tried using pdanet for the driver. I have tried a few different roms, as well: Darkside 2.4, 2.5.1, and gingersnap 1.21. All have had the same result.
When I plug the phone in, it beeps (charging) but no notification for usb settings (disk drive, sync, etc). On my computer, it pops up "USB Device Not Recognized" and says the device has malfunctioned, etc, same as OP.
In Device Manager, it shows under USB as "Unknown Device".
I have tried this with two Windows 7 laptops, and a Windows Server 2008 R2 desktop. Also tried with a different cable. This cable was able to transfer data from an external hard drive today, so I doubt anything is wrong with it.
Any help is greatly appreciated!

Well I had the same problem with a new sgs2 i got witb the warranty. I even made a post about it. Tried everything and nothing fixed it. Had to do another warranty exchange

Did you try the drivers separate first or Mtp mode
Sent from my revolutionized Samsung infuse
I tried without the drivers, and went to wireless and network > USB utilities. The only option in there, however, is "Connect storage to PC". If I try that, then plug it in, the phone acts like I hit the back/undo button. It doesn't show that anything is connected, nor does it give any other options. At this point on the computer, I get the "USB device not recognized" error.
This happened before installing Kies/Drivers, and still happens after installing drivers and kies.
try another usb cable
i had the exact same error, and it ended up being a good USB cable that went south
I will try a different cable when I get home - Have a month old cable for a mytouch 4g that I know works.
Okay, I tried it with the other cable, on a desktop in the rear port. same thing...Phone start to charge, and I get the error that the device malfunctioned, yada yada.
Any other ideas? Should I try to connect in Download mode?
Alrighty, so in the end, I ended up completely unroting, using terminal emulator to remove superuser.apk, busybox, and su and putting right back to read only. Then in CWM, flashed a stock 2.3.5 ROM (Zedomax). However, I now have the 2.3.5 ROM and the 2.3.6 KL1 Kernel...
I'm planning to return to Tmobile/Samsung - will the kernel and rom versions not matching be a huge red flag??
Any help is appreciated. I have tried to flash the 2.3.5 kernel, but I always get an error that it's not signed/verified.
Ideas?
I was hoping to grab the 2.3.6 OTA update, but it says there is no firmware update. Is there an update file I can put on the SD card and update using the stock recovery?
UPDATE:
I called T-Mobile Customer Service today, and went through the "troubleshooting" with them again. They ended up sending me a new one, overnight. They didn't ask anything about doing anything custom with it like rooting or other modifications.
I'm not sure if it made a difference, but I'm within 90 days, and also have the "best" insurance/warranty coverage through T-Mobile, and whoever their insurance provider is that I signed up for when I bought the phone.
Final charge is for $5, which I was told is some kind of fee from Samsung, but will appear on my bill.
Anyway, not too bad. Can't wait to get rid of touchwiz again when I get the new phone!

FYI, I just went through the same thing. Decided to finally root my phone after owning it for 2 weeks.
Phone nor the phone would recognize USB data, but would charge. Tried another cable and no luck.
Rebooted the phone. Works like a charm now.
Hi All, I've got a USB connection problem with my Galaxy Nexus. When I connect it to a computer, it will start charging, but doesn't show that it's connected to a computer and the computer doesn't show that a device is connected. I've tried on a few different Windows machines and don't get any change in the device manager. There is no "unknown device" nor device with an error. I've been searching the Internet and this forum, but still can't find the problem after a couple of days. Here's some details and things I've done:
I did not install the "force fast charge" kernel mod.
I've tried a couple different cables and verified that the cables worked with my wife's Galaxy II.
I've tried several different computers.
I've tried MTP and PTP storage options.
I rebooted everything several times.
I drank heavily.
I tried a factory reset.
I updated Windows Media Player to get the latest MTP software.
I installed drivers packages even though it never gets to the point of installing drivers.
Does anyone have any other ideas before I smash this thing with a hammer?
Does anyone have any ideas? At this point, I'm thinking there is a hardware problem.
Go into Menu -> System Settings -> Developer Options -> Turn on USB Debugging.
Not a guarantee, but something to rule out.
I've got USB Debuging on. Thanks for the reply.
Can anyone help? I'm having the same exact problem. My phone charge but is not detected by my computer. I am having this problem right after flashing AOKP ROM B35. This is very important, one mistake and my phone will be bricked as a computer to phone is so important !! There is nothing detected at all under device manager. Tried it on several laptop to make sure it isn't just my computer.
someone?
Uninstall the drivers you have for the s2. Reboot and install the official drivers for the galaxy nexus. Reboot. Then try.
If that doesn't work... let the phone load a while and just keep trying other ports on the computer. I saw this with my other gnex that it would take a while to realize a USB to be connected. Also make sure the USB is in completely... don't jam it in but make sure you know its All the way in. ( no pun intended) What's funny is my gnex will detect it instantly... but the other one takes a few tries.

Thank you dude. It doesn't work. Prior to installing this rom, my nexus is detected instantly. There is something wrong with the process i root or something. Now i can't do anything as It is not detected by my computer. Someone please help.
Indeed is the rom that is causing the problem. I opened NEXUS toolkit and rebooted my phone into boot image. It will sense it and i can operate from there. I've restored to factory and now my phone is being detected. I hope the thread starter gained something out of it too
I'm trying to root my Samsung Galaxy SIII, and whenever I try to connect it to my laptop, it gives me the "USB device not recognized" error. I have tried everything I can think of.
Kies uninstalled, registry cleaned, searched my computer to erase every file linked to Kies, and no dice.
Installed, uninstalled, reinstalled, re-uninstalled, re-reinstalled drivers. Nothing.
After every driver change, rebooted computer and phone, nothing.
Factory reset the phone since one post I found had that work, still nothing.
So right now I have a laptop with no Kies, Samsung drivers installed, a factory reset phone, and the USB cable still won't work. It is the cable that came with the phone. The phone is Android 4.1.1, an SGH-I747, build number JRO03L. This is extremely agitating since I can't even connect my phone to see the files on it! I had a Motorola Atrix and had a similar problem, but fixed it with a simple driver reinstall. I've even gone into the hidden code menu and set the USB mode to MTP+ADB, and the UDAP (or whatever) is set to PDA. That won't even work. At this point, I'm willing to do anything. I hate stock ROMs, and want to remove all the crap this phone has on it, especially that damn voice thing and Kies.
self bump, since it's been three or four days with no reply. I could really use advice on this.
In your laptop, when you go to Devices manager, do you see an unknown device? If you try searching online for the appropriate driver through Windows Update, does it find any helpful driver?

I was dealing with this on my Win7 rig, and came across some advice that helped. If you have an SD card installed, turn the phone off, remove it and then reboot and connect the phone to the computer. I don't know why it worked for me, but it did.
Good luck to you.

Possibly two things download revouninstall to uninstall your drivers it searchs bolth registry and system for left over files (delete them)
I had same problem all I did was use revouninstaller to uninstall old drivers (it scans entire system and registry for left overs. a must.
Then I used these drivers, also when letting your installing drivers (turn internet off) don'lt update them there older, but they work for everyone who does this. If you need a better guide search there is one somewhere but point is use these drivers and don't update them (smile) works with adb everything you won't see a difference these drivers work better. peace.
Drivers------>Samsung Drivers 1.4.6.0 search for 1.4.6.0 drivers samsung fix for more info later
search for revo uninstaller
Whenever I have this problem, I must manually install the driver.
Open device manager.
Go to the unrecognized device that you know is your phone.
Properties and "update driver".
Tell it you have your own driver.
Don't let it "search" for a driver.
Manually point it to the exact driver file you need.
Works every time for me.
I took out the SD card to try all possible solutions posted.
Uninstalled drivers and installed the older versions that one of you linked me to, didn't help.
Tried directing Device Manager to install the driver manually, but I have no idea where to find it. If you have the driver file or at least the name and version, I can get it and use that.
I can't believe how much trouble it is just to hook an android phone to a computer, this happened with my Atrix as well.
Have you tried and different cable ?
So I was having a problem with my laptop recognizing my S3 when connected via USB. The notification would not appear in the status bar that a connection was made, and neither Fedora Linux or Windows 7 would recognize that the device was connected. I tried reinstalling Kies/drivers under Windows, and checking the output of dmesg/lsub on Linux. Nothing.
Did some googling and found this thread that help solve the problem!
http://blog.vacs.fr/index.php?post/...ot-detected-problem-on-Android-Samsung-phones
I found the problem. It was the cable. Somehow, it was severed where the cable connects to the mini-USB connector. I discovered this when the entire mini-USB piece fractured and fell off, revealing the tangled and snapped wires. I went today to AT&T to buy a replacement, and it worked on the first try. I don't know how the cable got damaged like that without being detected, but there we go. Now how do I set a question as resolved?
Hello,
All of a sudden my LG G4, Model 815 can't be recognised by computers anymore. Tried different PC's, with different OS, also have tried different cables. I have been using official cable that I found in original package and everything was working good, but now the phone only shows charging and PC's are showing popups that usb device is not recognised.
I was doing a little reasearch and already tried some simpliest things - reinstalling drivers, tried different cables, different PC's. For example my cable works fine with HTC M9, but doesn't do the thing for me anymore. And vice versa HTC cable works for HTC and does not for my LG. Also I found that you must simply select "charging" in top of your left corner and just select MTP. The problems is, that is not shown in my phone anymore. I'm thinking of trying to do factory reset, but before that maybe some of you have some thoughts? Could it be my phone hardware problem? Before a couple of days ago when everyting was working fine, I did not do anyting unusual, also that phone was never rooted, so I can't believe that it is somehow broken. I have it for nearly three months I think.
And yes, I understand that I can simply transfer my files through, for example AirAndroid of similar apps, but I cannot stand that error sounds playing on my laptop when I connect my phone through the cable to charge it.
Now it is running Android OS 6.0 (marshmallow)
LG G4 MTP Transfer Broken
Hello XDA,
I am having the exact same issue. MTP worked fine and then one day stopped. I believe it happened when I tried to transfer photos from phone to computer via USB and File Explorer. The transfer started, then after about 3 images transferred I received an error, "file transfer the system cannot find the file specified", after that the USB logo disappears, it will disappear from Device Manager, it will not even charge via USB. A phone reboot will fix the USB charging, but the option to switch to MTP is gone. I can't which it in in Developer Options either.
I've also tried all the same things LocaSnai suggested. Such as, different cords (3 of them), windows drivers, LG Air Drive, LG PC Suite, and LG Mobile Support Tool, Verizon Wireless Software Upgrade Assistant, of which none will update or repair the phone. I've also restarted Media Storage service (force stop and reboot). My Nexus 7 tablet connects perfect every time using the same 3 cables. The wife's i phone 6 also connects without issue.
I have performed a factory reset and MTP worked UNTIL I restored the LG backup. Then it went back to the same issue. Factory reset was a LG Support idea. They said that if it happened after the factory reset and back up restore, it could be a virus or issue with an app. How would we go about detecting what is wrong?
While working on this message I tired a few new things. I am able to get MTP to show up (not work as it used to) by plugging the phone into power, and then unplugging and plugging into USB. Each time, MTP will recognize (I tried all the software above when MTP shows up, none recognize the phone.) If I unplug USB and plug back into USB, MTP will not show up, only charge will. Have to plug into power then back to USB (I am using two cables, one in the brick and one in USB. Nexus 7 will work as expected with the same two cables). Some times I see the Yellow Triangle over the LG UBS entry, but following this tutorial doesn't work: www.verizonwireless.com/support/knowledge-base-161810/ Uninstalling the driver and letting it reinstall.
My phone is as original as the day I bought it. ie not rooted or tampered with. Android is up-to-date.
Thank you in advance to the kind folks who offer assistance!

I had the same problem (at the same time I had problems with my sim and my message light was showing a dim green..), tried everything, drivers, cables, at the end a different pc and then I rebooted my phone while It was connected to the 2nd pc, after this, every problem was gone and I good see my phone again in windows. Now after a few reboots with and without the connection to a pc, the phone seems to be working as usual again...
(and My phone is also as original as the day I bought it. ie not rooted or tampered with. Android is up-to-date.)
Doorwerth, thank you for the suggestion. Tried that a few minutes ago and still have an issue.
I'm considering this next: LG G4: How to Boot into Download Mode. I think it's a bit extreme.
