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 .

as I said I tried back usb and also front usb... same problem...
debugging is also off...
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
Sent from my GT-I9100 using XDA App
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.

Thats your PC port USB 1

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 .

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 connect my device to my laptop as well as desktop using my usb cable and other and the device is only charging and the usb menu doesn't appear on the phone . Pls help
Hello guys. I have one problem with my device, as it wont connect to mi pc suite, even i turn on usb debugging. Anyone have same problem? And any software required usb debugging connection also failed to connect with this phone. Anyone have solution? Windows 10 btw.

Did you try to change your USB Connection setting from 'Charging' to 'File Transfer'?
Also, if in case you're using a cable other than the provided USB-C data cable, are you sure that it's a data cable and not just a charging cable?

I already tried usb debugging on, with file transfer/charging and debugging off with file transfer/charging. and I'm currently using original usb c. I always get this error saying that my device must be updated first (see attachment) , but I already at latest miui. I even formatted my windows lol, still no luck. But I still can transfer file between my pc and phone using windows explorer.
