Today I plugged my phone into my PC and used a USB port of my computer case. It didn't work. Windows said connection to device would be lost, couldn't copy any files. I then switched to a port directly on the motherboard and it worked flawlessly. Any ideas why?

I have a problem with usb connection with PC. When i plug the cable, usb debug is active, but my pc doesn't recognize the phone...I tried to uninstall drivers and htc sync program and install them again, but still don't work..
any ideas? the only way seems to be restart tattoo with cable plugged, and pc recognize tattoo, but not always..
maybe solved, I put pc sync into taskiller ignore list. now seems to work
My problem is little weird so i try to explain it as best as I can...
until today there was no problem to connect phone with USB but now when i connect the phone windows said "This device can peform faster this usb device can perform faster if you connect it to a Hi-speed USB 2.0 port. And another problem is when i turn phone into download mode start odin and connect the phone it said... usb device not recognized. I didnt flash any rom yet and i try different cables.
I am running on windows 7 ultimate 64-bit. I try two different PC and its look it the same problem.
But the weird part is that on third PC which has also win 7 ult 64-bit it works just fine.
So i try reinstall operation system but the same problem. The computer is max 3 years old so its has for sure usb 2.0
So i am little desperate because i am not sure if its problem with computers or with the phone.
Thank you for any advice!
I always had this problem with the i9100 actually, I blame crappy usb drivers.
Kies installed? Did you also try different usb ports? Chipset and USB Drivers of mainboard installed?
yes kies installed and also try back and front usb... but same result...
and usb drivers are installed manually by windows as far as i know... or?

Standard Windows message for USB connections just means what it says .
And another problem is when i turn phone into download mode start odin and connect the phone it said... usb device not recognized.
Download mode how and whats on the phone in download window
Connection must be to a mainboard usb port .
If your PC has Kies make sure its not running make sure USB debugging is off on phone .
Power phone off restart start Kies connect phone does Kies see phone .
If yes turn Kies off remove cable connect phone in USB mass storage mode wait for windows to install drivers . Does PC see phone in Windows Explorer .

I try a little experiment... removed external grahics card and plug graphics on mainboard... and for a few seconds its works!
I try copy some video and speed was usb 2.0 but after few seconds its get error cannot copy bla bla and windows popup : this device can run faster and it change back to USB 1... weird...
and also i try again downloading mode but the same error... usb device not recognized...
Have you always used the same USB-port?
On some pc's, they only have one or two high speed ports and the other ones are "slow".
So yeah, try an other USB port on your pc

OP, I am confident it is a problem with your PC, and this XDA forum won't be able to help.
Try using another USB 2 device (like an MP3 player), see if you get the same message.
Use a different computers with the SGS2, see if you get the same message.

USB port not getting enough power .
Its PC not the phone explore sees phone and Kies sees phone = USB drivers ok
USB ports are not all usb 2 check your manual .
You can try factory reset on phone this will wipe all data .

Use a mainboard USB port they are USB 2 but it matters not a jot about 1 or 2 .

hey guys.
i've been using the xoom for about 3 weeks now. i have the latest motohelper driver. i'm using windows 7 x64. i've been able to access and transfer files before no problem. I rooted over a week ago and also have had no problems moving files around. accessing the sd card from the pc has also worked.
now yesterday I send my wife to move a file over, and she tells me it's not working. sure enough, no matter which usb port on the pc I plug it into, or how i disconnect and reconnect the cable on the xoom, windows gives me the USB device not recognized message.
I've tried rebooting both the PC and the Xoom. i've reinstalled the drivers. i've enabled and disabled usb debugging on the xoom. still get the same message. under device manager it shows as Unknown Device. if I go and manually select the Motorola MTP drivers it tells me it can't start the device.
we haven't done any recent software changes on the PC or the Xoom. specially not within the last two days for it to go from plugging in just fine to USB Device Not Recognized.
any suggestions?
thanks.
When connecting my Le Pro3 to my windows 10 PC it doesn't detect it at all. There is nothing that comes up in the device manager for it. I've tried changing the USB debugging option and rebooting the phone and PC but nothing seems to work. What I'm trying to do is get adb to see the device, but I can't even get it to come up as USB storage. Has anyone else had a similar issue with the Le Pro3?
Try anotherr USB cable and another USB port, preferably one on the rear of the pc.
Apart from that no ideas at the moment, sorry.
I think it is USB port issue. My laptop have two USB 2.0 ports and 1 USB 3.0 ports. the phone is only detected at my usb 3.0 port not 2.0.. if i connect to 2.0 it will just charging and no usb option pop up. but 3.0 everything works fine
Mine had problem with sync. Can transfer from some files but imposible to in music folder. Wipe helped. The official one, x720, 18s.
Had this issue. Attempt turning USB debugging OFF. Then plug it in. Allow windows to completely install devices drivers. Then do it again with USB debugging on.
I think I fixed this issue by uninstalling the Le Pro 3 drivers in Device Manager and plugging the phone back into the PC. Not sure why but that worked for me. My laptop is Windows 10.
I fixed it by using a different cable. I used a micro usb cable with an adapter. I don't know why the stock cable wouldn't work

Yep, disabling USB debugging in the USB connection menu works!
I did this from this video and it worked.
I got this problem when I got my phone.
The problem was that I was using an USB extention to try to connect to my PC. Just plug ur TYPE-C cable directly to the usb port of the PC.
Hi guys,
i tried to root my OP5 (OxygenOS 9.0.10) but i couldn't even start.
My Pc and 3 other Laptops won't recognize the Device - while my OP7 connects just fine.
I have tried the USB debugging, the preference set to File Trasfer (MTP) and other dings in DEv Ops.
When i connect it it only loads without any symbol/popup about the usb mode.
