Hello I have a touch pro 2 with tmobile and my computer does not find the device even in device manager there are no drivers in there at all
Even when I was watching device manager unplug and plug back in there was no change showing that there was nothing done on xp and vista and two different computers and thee different cables that work on different devices just seems that only this phone is not detected any ideas would greatly appreciated
I had this problem once... I re-downloaded the software from the provided disc... from microsoft... nothing... I even got T-Mobile to send me a new phone... it did not recognize it either... this left me with one option... restore! Appearently I accidently deleted a file I needed and I could not find a way to restore it otherwise. That was the last thing I tried obviously... it worked. So use a restore point before it stopped recognizing your TP2
hum never did see it. Two operating systems on one pc one was fresh xp install new and another pc running xp as well. All three did not find it at all even master reset the phone thru options couldn't get hardware method to work

When the phone is connected via USB to any of those computers, does the orange light come on at the top indicating it's getting power through the cord?
Hello, XDA-Experts!
I encounter a problem with my desire HD and looking for any help I can get.
Since about one week my Phone is not recognized when connected to a PC.
I am using the phone since December 2010 and it works well since then. It's S-Off and Radio S-Off. In the moment, I am using CoreDroid 4.9 with Radio 26.06.04.06_M. Before I was using the ARHD ROM for some time.
The problem occurs on 3 different PC's with 3 different operating systems (Server 2003, Win 7 Ultimate 64-Bit, Win XP Pro SP3, all of them used to recognize the phone before). Windows never recognizes the phone now, android (in most cases) recognizes the connection an asks for the connection mode. The phone is ALWAYS charging over USB.
What I tried so far, after searching in different forums and via Google:
- Rebooting the phone
- Removing the phone's battery
- Booted in fastboot - no USB connection
- Tried a different USB cable
- Changed the USB ports at pc (without hub, no other USB-devices connected)
- Flashing other ROM (tried CM and MIUI, with full wipe/factory reset)
- Checked the USB-connector in the phone with an electronic microscope - all contacts look fine
I am running out of ideas, the only thing I couldn't try, is another radio, because I don't know how to flash without pc. But I don't think, the problem is related to the radio...
Any help is greatly appreciated.

Your device manager shows anything when you connect it to your pc?Debugging mode is enabled?
Device Manager shows nothing. Debugging Mode is enabled.
I went through a similar problem a while back - took ages to resolve it - in my case the problem was the usb cables I was using - I had tried a few - but its possible to get cables that only charge and dont communicate - eventually i got it fixed by using a new original cable.
Might not be this for you but it certainly helped me
No fix that I know of...
I had this problem...
I tried different computers, different SD cards, I could take the sd card out and put it in a usb holder and that would work fine, so it really wasn't the sd card. I tried different usb cables too.... nothing would work.
I spoke to my carrier (Orange) to see if they could sort out the problem, and they went through their 'script' of diagnostics and came to the conclusion that it was my computer drivers and there was nothing wrong with the phone!!!
I then rang HTC and after several phones calls later, they said that they would repair it, unfortunately that would have left me without a phone for 2 weeks, so I rang Orange again to demand that they replaced the phone! I told them that HTC had said it was a fault and they sent out a replacement Luckily I had not rooted it at this point, so it was easy for me to swap it.
The replacement phone came the next day, and like magic, worked fine when I connected it to my computer (the same one that apparently had faulty drivers!!)
So, I never found a fix for this, but managed to get a replacement! hopefully you will be able to sort something out...
Good luck
I had this problem once and it turned out to be kernel related, but I'm not sure if this would apply in your case since you've flashed a few ROMs and still have the issue. Still, might be worth trying one of Apache's Buzz kernels or LeeDrOiD's latest... if only to rule out another possibility.
does your PC recognize it if you mount the SD in recovery?
if not, it should be the cable
I had the same thing, I went crazy, and somebody told me to use another cable
and worked
Same happened to me.
Seems the phone crashed the USB controller or something on the PC.
A reboot of the PC fixed it for me (I dont see you mention that anywhere).
First of all, thanks a lot for all your replies!
As I said before, I tried 2 different cables, that both worked fine before. But after your replies I tried a third, new one - same result.
The card is recognized fine by windows when I put it in a USB-Card Adapter.
What I forgot to mention in my initial post, is, that I also formatted the card in my pc, put it back in the phone and started the phone new - same result.
I will try some other kernels now. B.t.w., has anyone a solution for flashing the radio without pc? Via terminal, or recovery? As this is one of the few things, that I couldn't try yet.
I'm 99% sure radio wont be a factor in this mate as they only deal with mobile connections, eg GSM/3G, Bluetooth, WiFi and GPS. If the problem is software and not hardware then I think it will be with the Android USB gadget driver, which is in the kernel. Someone please correct me if I am wrong.
Can you mount as usb in CWM?
No, that doesn't work either.

1) Try reinstall HTC driver on your windows and try again.
2) If it failed, backup all your files on sd card via USB-Card Adapter. Then use SD Formatter 3.0 (google it) to format the sd card. Copy the backup files back to SD card and try mount the usb again.
HELP i got the same problem
I use the phone in the last 6 months; I have S-OFF, clockworks custom recovery and rooted stock HTC 2.2 Froyo. The only change I made last week is purchasing a desktop cradle "stand". I tested the stand several times the last week and I was able to access the SD card & the HTC sync modes successfully.
Now when I connect the phone using stand or any other USB cable including the original HTC; nothing happened on the computer! The USB manager activates and brings up the USB connection type menu. However, nothing recognized by PC.
I tried all things that you can expect (another PC, another cable, factory reset, new room, with/without cradle) nothing happened, even I connected the phone on a new PC it didn’t detect the new driver!
What to do now??
Hi,
Not sure if you have already, but you can try the new HTC sync version 3.0.5557 - It's actually for the HTC flyer tablet, but i installed it and it works perfectly for the DHD.
You might have a driver issue, but the new 3.0 sync comes with new windows drivers so maybe it's worth a shot.
I've checked the HTC Flyer support page but there's no link there for the 3.0 Synch ... I could only find a direct link, here below
http://www.htc.com/www/SupportViewNews.aspx?dl_id=1097&news_id=923
Be sure to un-install the previous HTC sync first
Its not a driver issue, I tried the new sync. Not working. Nothing is working with USB only the charger.
I have a feeling that electrostatic damaged my USB. I remembered last week I touch the phone while charging and a one electrostatic click was strong.
help!!

hey I have same problem... :-/
what's the solution ?? plz tell me
same problem
please help
I've got a Desire HD (since Jan. 2011) witch i always sync using WiFI so i never need to use USB other then for charging my phone, i did install HTC Sync and it worked fine when i first got my phone but found it to be a program witch i don't need so when i reinstalled my PC i didn't install the HTC software and Drivers.
Last week i decided to root my phone using the "Advanced Ace Hack Kit" but was unable to get working because the phone didn't connect to my PC, after a lot of testing ( @work ) using 4 different PC's with Windows XP, 7, Ubunto Live and BackTrack 5 live, it seems that i just can't communicate with my phone via USB (Windows device-manager does not show the phone eighter), i also used 2 different USB cables and severals different USB ports on the mentioned PC's but to no avail.
This is what i've done so far...
Set option "USB Debugging" to ON
Set the phone's "Connect to PC to.." to "Charge Only" (also tried HTC Sync and Disk Drive mode)
Installed HTC drivers v3.0.0.007 from Ace Hack Kit on WinXP and Win7 PC's
Installed HTC drivers v3.0.0.008 from HTC.com on WinXP and Win7 PC's because v3.0.0.007 didn't work
Booted from Ubunto Live and BackTrack Live
Set the Phone back to factory defaults and tries the above again
Installed HTC Sync on WinXP and Win7 PC's
After all this the problem stayed the same, i'm just not able to get the phone to communicate to any PC, not via "HTC Sync", "Disk Drive" nor via "Advanced Ace Hack Kit - Charge Only"
Charging the phone works fine btw, i charge at home and at the office using a desktop cradle, the same ones mentioned in the article below
http:/ htcpedia.com/news/supreme-desktop-charging-docks-htc-desire-hd.html
So what do you guys think, is the USB port on my phone broken..?
try to flash again or other ROM.
yesterday i also face same problem, after format all and flash other ROM then ok already.
i also don't why this happen.
Are you using the cable that came with your phone? I bought a cable off ebay and it only charges, doesn't have the ability to send/receive data
yes, some cable is only for charge. Are you using the original one??
@christeohlg
i can't flash any other rom since i cant root my phone via USB.
@maatsby
yes, i am using the original HTC cable i also tried the original cable that came with the Desire Z that my wife uses but unfortunately no change.
I have seen this issue quite a few times and I think that it is ROM related.
It happened on a HTC Hero, a Samsung Galaxy Europa, and a LG GT540.
I too thought it might just be the cables but every single time, a wipe and new ROM brought USB functionality back.
Oké, i understand that some Rom's might have questionable USB performance or might disable USB because of a bug or something but my Desire HD still has the custom HTC v2.3.3 Rom on it, it has not jet been rooted nor has the Rom been replaced by any custom Rom.
So is the Rom would be the problem i would expect more people would have come foreword with this problem.
I too am having this problem, except I bought mine second hand. I am very quickly coming to the conclusion that some part of my phone usb port is broken.

I had the same problem but I was messing around with different kernels. Try flashing to a different kernel or reflash your rom. It worked for me!
The device acts as if it is being charged.
Steps I have taken so far:
-uninstalled T-mo Samsung mobile drivers and reinstalled
-deleted (uninstalled) ALL recognized USB devices via USB deview
-tried to connect without Samsung drivers installed and all USB devices uninstalled
-tried to connect with Samsung drivers installed and all USB devices uninstalled
-tried to connect without Samsung drivers and other devices installed
-tried to connect using safe mode, both with drivers installed and not
---**these are both trying with the current one provided on Samsung's site (1.5.14.0) and with the one found here on XDA from 25apr2013 (1.5.23.0)
-tried to connect using different USB ports
-tried to connect using a different USB port on a different USB controller altogether
The kicker:
Device is recognized instantly... on my laptop.
This means:
-It is not the USB cable I am using (even though I have tried 3 different cables altogether regardless, including the one that came with the phone)
-It is not the device itself
Possible: Windows issue? Last time this happened was long ago when I had gotten a MyTouch 3G Slide. I eventually just reinstalled Windows since I had been meaning to then. I don't want to do it now though because I have too many things installed on here to start a fresh install... but I suppose if nothing else works, that's what I'll have to do.
Before that though, I would love to hear any other suggestions from anyone here.
Some time the fault cud be the cable itself... I had same issue months ago my original samsung UsB cables didn't worked... It olwyz show the msg UsB not recognized... Then I tried with a different UsB cable (i had a Nokia UsB cable) and it worked...
Try it...
Cheers!!!

As stated, I have tried to use two other USB cables aside from just the one that came in the package.
Since all cables work on the laptop, but not this computer, I have pretty much singled it out to be a windows or a driver issue. :\
What are the specs of your desktop and the specs of your laptop? You claim it is a windows issue so I assume your laptop (that recognizes the phone) is not windows? Do you have Kies on the PC? If so, try to uninstall it completely and then install the individual drivers. Also, maybe just try updating Kies. You wouldn't need to install it, just download to your PC should work. As far as that goes, does Kies recognize the phone when plugged in at all? Does ODIN recognize the phone when plugged in? Maybe some of this will help you to find out if it is a driver issue or not. Good luck.

PC is i7 920, 12GB DDR3, Intel x58
Laptop is i5 2430M, 6GB DDR3, Sandy Bridge
Both are Win7 Pro, neither have Kies (I always just downloaded the drivers themselves) but I'm downloading it now to give it a try. As of now, nothing recognizes the phone on PC.
Kies method didn't work either
I did "Troubleshoot connection error", which I guess reinstalled the driver, but it still didn't work.
Getting ready to dig out that Win7 Pro CD at this point... :\

Enabling dev options and USB debugging was the first thing I did once I turned on the phone. Tried it both with and without, still not recognized either way. Still recognized on laptop.
I've also reinstalled windows altogether, since that fixed my issue last time around, but it's no good this time still. Clean install, formatted. No good. Previous steps from first post also taken, still no good. Tried the PDAnet method as well, no good.
At this point I am wondering if it might be an x58 issue, which would really suck, but it's the only thing I can think of given all the steps I have taken.
Okay... so what's the trick on getting Windows 7 x64 to recognize this device in Download Mode?
I have enabled USB Debugging. Tried several different ports on my Maximus V Extreme motherboard. I have tried using the PDANet drivers. Nothing works.Windows will prompt me with the "Device Driver software was not successfully installed" message. Anyone know a trick?
EDIT: FIGURED IT OUT. The last Android device I owned was the Galaxy S2. Now, back then it was understood that one should avoid Kies like the plague. However, in this case, it solved my problem. It installed all necessary drivers and I was able to communicate with ODIN. Cheers.

I might have pinpointed the issue!
I tried Kies again, uninstalled, reinstalled, updated. No go. I did Kies by air and got a connection! So It's gotta be something with the USB.
Although I thought it was weird, I think it might be an x58 issue, I decided to pursue that anyways.
I found out that USB issues are common with x58 (per this forum: http://www.evga.com/forums/tm.aspx?m=159610 ) and will be trying a fix located here: http://www.evga.com/forums/tm.aspx?m=442244&mpage=1
I'll report back once I try this out. Hopefully it fixes it.
If not, I just ordered another USB 3.0 controller (completely unrelated, it doesn't need to be USB 3.0, just a different controller altogether, but USB 3.0 is backwards compatible anyways. I just needed one for blackmagic) which was PCI-e x1 (still dependent on x58, so it wouldn't have mattered, check diagram on fix link), which I WAS going to install in my PCI-e x1 slot, but that would have not worked! Going to install in a PCI-e x16 and hope for the best.
I'll reply back once I test that out too.

In case anyone was wondering or stumbles upon this later, I have a few updates.
I got the USB controller today and plugged it into the PCI-e x16 slot, plugged in the S4 and it worked completely fine.
I also contacted EVGA about the issue and will get an RMA, so perhaps it's just a faulty unit. However, this seems rather common (refer to previous linked threads) in x58 chips.
I imagine it has something to do with power distribution with the controller, which is why upping the ICH voltage fixes it for some people. The USB controller is powered via 4pin, not dependent on Southbridge. I guess the S4 has higher voltage(?) requirements for it to be recognized. It seems rather strange since my other devices are still recognized, but well, that's what I managed to come up with.
Cheers.

Here's my craziness.
USB connection was working yesterday. Today, it is not.
I have uninstalled/reinstalled the Samsung Windows drivers/Kies
I have even adjusted my southbridge voltage to 1.2V in my BIOS
Still, no joy.
Curiously, when I boot the phone into download/ODIN mode and connect it, ODIN recognizes the connection. Reboot back into normal mode, and no USB connection is recognized. It is not showing up in my Device Manager as an unrecognized device. It just doesn't know it is there (unless phone is in download mode).
UPDATE: Solved. I had installed this ROM (http://forum.xda-developers.com/showthread.php?t=2261013). Reading back over the thread, it provided instructions for re-enabling the USB recognition of the phone. Had to re-enable the developer options and reset USB debugging. Makes sense now.
HI
I'm facing this issue today, I've tried two different laptops, both have Windows 7 x64 installed. I've tried every USB port on the two machines, I've tried with three different cables, I've downloaded and installed every USB driver there is. no use!
I'm out of options here and I can't think where to look further.

很想帮你啊 可是英文水平比较拙计
ok so now I'm guessing it is not windows, I tried on another machine with Windows Vista and got the same error.
any thoughts, anyone?
Did a factory reset for the phone
no it works!
don't know why
I just picked up this phone a couple days ago and last night tried to get the USB to work with no luck. I've tried everything I can think of. It does work in PTP mode but not MTP mode. I was able to use odin to on it though, so I was able to root it.
I've tried both in linux and on windows xp. I've never had an issue with any phone on linux and have installed/removed drivers numerous times on XP.
Tried 3 different cables, Factory reset with and without USB installed, tried pretty much everything I could find while googling similar problems (removing old registry entries, installed media player, etc)
I have adb installed on my linux box and even with debugging enabled I can't even get adb to connect to the phone.
Definitely something strange going on. Maybe I'll switch to cm10.1 to see if that makes a difference
I cant get my computer (windows 7) to connect with the phone when the phone is on, and was hoping some one might have found a fix.
This might fix it...

Here's a link with a list of things to try what you may not have tried to fix your problems.
A small number of devices I have worked on have a weird thing, that the first time I plug the cable into the computer, it connects but won't show up on the screen. unplugging the USB cable from the machine for maybe 3 seconds, and reinserting makes the connection work... go figure! :>)
Aloha and Good Luck!

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.
