2 days after I fixed the USB port the computer doesn't recognize the device.
#I tried 3 cables.
#HTC sync Maneger installed.
#Drivers installed.
#The device show that the USB cable is connected, but nothing on the computer.
I've tried everything and nothing work.
Someone??
Just a shot in the dark on this one, as I'm not familiar with hardware surgery like changing the USB port. But this is worth a try:
Try going to Windows Device Manager, see if the phone shows up. If so, pick the option to manually install drivers, and try the generic Android MTP drivers. I sometimes have to do this, to get the PC to read the internal storage.

Hi guys, I'm obviously new here, but I did have a look and couldn't seem to find this answer anywhere else.
I'm trying to hook my HTC Desire to my PC, but every time I connect it via USB cable it says that device drivers are not found and that Windows cannot rectify the problem.
I've tried installing HTC Sync, but the PC won't even recognise that there's a phone or mass storage device hooked up, so it just stays at "disconnected".
I've selected the phone to appear as a mass storage device when I plug it int the PC (I even select this on the phone's display as I connect it via USB so the phone realises that it's being plugged into a PC).
Does anyone know how to fix this?
Thanks in advance.
I've struggled with a problem like this before (though, a flash drive, not a phone).
There were two solutions that helped mi on two different occasions.
1) Removing all usb devices from the computer. Shut the computer down, take out the power cord and wait for 20-30 min to settle all capacitors. Then turn it on and plug the devices back in.
2) Put the device in the computer as Mass Storage. Go to device manager and see where is the device. Right click on it (should be unknown or stuff), choose update driver. If it doesn't find anything try updating windows with latest patches and try again.
3) I was solving a non-detectable usb webcam, but removing ALL usb devices from the device manager (Under USB choose device, delete, choose device, delete.) Then click Scan for changes on the top to refresh the devices and install the drivers of the usb root hubs, etc. This would probably fix the problem if the above fails.
---- edit ----
Quick note: if your keyboard/mouse are USB, you could hang without keyboard or mouse until you restart your computer, so keep in mind if you can detect them, delete them last

If you still can't get it to work, please provide results from another computer (if it works there as mass storage), or better if you have some Linux Live CD you could try there if it gets recognised.
Where you try to plug usb cable into PC - front panel or rear? Because a lot of PCs have an issue with front panel usb. Try rear panel

Thanks to both of you for the swift replies
I actually figured I'd check this short fix before trying the more detailed ones and it seems like it was just a matter of plugging it into the rear usb!
I'm definitely putting this solution to my personal FAQ. Thanks, jankos.
HTC EVO won't mount as a drive
verified that issue was with the front USB port. I plugged my EvO in to a usb hub I had plugged into back usb port and it worked like it was supposed to.
I've searched google/xda and no one seems to address this very clearly.
I was having problems connecting my SGSIII via USB to my computer(s). Yes, I was using the cable that came with the phone. When trying to simply transfer files via USB (MTP or PTP) windows would not recognize the phone and a message saying "usb device has malfunctioned" popped up from the notification area of the taskbar. I had all of the drivers installed. I tried connecting the phone to my laptop (thinkpad) and desktop (homebuilt) computers, which were both win7 64bit. I tried every single USB port of each computer. Sometimes the device would show up in my computer, but I couldn't access any of the files. I was able to get odin to recognize my phone, however, and (foolishly) tried to flash a rom to my phone. Odin would fail every time at a different point in the process. I was stuck with a phone that would not bootup.
Then, I tried a computer (old dell, win XP) at work. I tried to flash the rom with Odin again. On the third attempt it worked! (after changing to a back (instead of the front) USB port) It was a big relief that I didn't brick my phone. Also, with this computer I could connect to my phone via MTP or PTP. I thought, therefore, that the problem was win7. So, I went back, installed win XP on my computer at home. This computer would still not play nice with the phone. (USB device malfunctioned error appeared again.) So, if you're having problems try a different computer. I had to try 3 before I found one that worked.
TL;DR: Try a different computer and different USB ports on that computer before you give up on connecting your phone to a computer via USB.
Finally, I NEVER had these problems with my HTC Hero, or HTC Evo. The phone would connect to ANY computer or ANY USB port. This was true for transferring files and for ADB also. With my S3 I'm transferring files by removing the SD card and connecting that to my computer. Kind of a pain in the ass. Thanks samsung.
When I plug my handset to ANY computer (with, without kies or drivers, it doesn't matter) the phone charges, but, nothing appears on the computer (no unknown device or recognizing the two drives of the phone, but not mounting them (as it did before)) on the phone.
The "USB" icon doesn't prompt and if I go to settings/wireless and network/ USB utilities, when I touch the USB mass storage button, it prompts me to connect cable, which is already connected.
-USB debug isn't activated (I've tried both)
When my phone is powered off and I start to charge it, the charging screen doesn't prompts, It just start booting.
I've tried different USB Cables.
The Phone is Official Stock Never Rooted (I discovered this trying to root it today)
Am I SOL if I want to root it without a working USB Data port?
Any ideas?
i would say make sure there's no dust/ buildup in the port. I had connection issues once to find a pocket lint cramed in there. next do all the other stuff. uninstall/reinstall drivers, diff usb port, diff pc, reboot. My symptoms were similar to yours but i was able to reboot into recovery/bootloader and use adb/fastboot no prob, so not sure. and I was already rooted/twrp recovery. might be worth it to try fastboot in bootloader just to be sure and get a recovery on it asap. If that works you should be able to recover stock or flash whatever, then test usb again in diff pc with fresh kies install. good luck.
Sounds like bad/improper USB cables to me, not all USB cables support data and charging, make sure you're using an official Samsung USB cable.
If you have a friend with a Samsung smart phone ask to try their cable.
Hi, my phone stopped being able to get a USB data connection. The port is physically intact and does not wiggle. I've tried two different Macs and one PC, different USB-A to -C cables (all verified by Benson Leung). Also toggled USB debug, MTP and PTP modes from Developer Options, rebooted phone and computer. When I plug the phone in, it only goes to Charging mode. Android File Transfer doesn't see it and 'adb devices' comes back empty. There is no notification offering me to select connection type. Did I miss anything or is it time to send it in? Thanks, Tony
What OS are you running on your Windows - checking your Device Manager under Control Panels - are all the Google / N5X drivers installed and working correctly before this ? Try uninstalling, reboot PC and re-install them - and, use different USB port to connect the cable (what kind of connections are you using ??)
Can you run ADB ?
Thanks I'm primarily using a Mac (10.10.5) but the PC was running Vista. It was a borrowed PC so I didn't install the drivers. I don't think it's a driver issue though since nothing shows up in device manager and the phone doesn't offer to switch out of charge-only mode. Also the same Mac worked previously.
Hey so i have been having a big problem recently. my htc one m8 32 gb verizon version doesnt get recognized by my computer. ive tried different computers, ports, and cables. i even got a new charging port and installed it but nothing. when i plug my phone into my pc, nothing pops up. the phone only charges but no option to transfer files. htc sync says no phone connected. Also have usb debugging enabled but nothing. running on 6.0 marshmallow and any help would be nice. Thanks!
If you look at your notifications, there will be one you can't clear saying USB Charging this device. Click on the notification and change it to File Transfer.
Couple comments:
1) Try the genuine HTC cable that came with the phone. I've noticed that some 3rd party cables will only charge, and not connect by USB/MTP. I assume the pin layout on those particular cables is not exactly the same as what HTC uses.
I know you probably already tried this (HTC cable) but this may at least narrow down the variables.
2) Assuming a Windows PC, go to device manager, find the phone (hopefully, its listed) then select the option to manually select a driver. Then pick the generic driver for "Android MTP device" (or something like that, forget the exact name). If often have to do this to get my home PC to "see" my M8 by USB. Although my work laptop doesn't have this issue. Your results will vary depending on your exact PC configuration, it can be very confusing and frustrating!
m8 problem
First sorry for bad English.
My M8 is not recognized by my computer. I've tried extra ports, cables, drivers .. Windows 7 64 bit is computer, android 6 is on the phone. Only the phone detects it is connected to a computer and offers the options, mtp, ptp, charging ...
What can I do?

I don't see what the problem is. The PC recognizes the phone. Are you trying to access a function such as fastboot or adb, that is not working? You never say in your post what the problem is.
