HELP!
I'm a new to PPC. I've got an O2 mini, I charged the device well just now, but now when I connect the device to my computer, always says that the USB device is not operating well and windows can't recognize the device. Is there anyone could let show me what's wrong? what should I do? Thanks!!!!!
Hello,
Are you sure you have installed Active sync in your Desktop?
Regards
Carty..
Is your USB cable plugged into a front USB port on your computer??
If so, try plugging it into the back. Some front USB ports do not have enough power to recognize the MDA Compact, and you get that same "USB not recognized" error. Most back USB ports are powerful enough.
uninstall activesync ... reboot system install again ! should work
the comupter may of just seen the modem side of it it happened to me you need to go into your hardware file on your pc and delete any modems you don't recogonize (carefull you don't delete the wrong one (i exepct no responsibility if you do)) and then re install active sync v 4.1 fom microsoft site. then plug it in again good luck
Thanks all you guys. I have got this problem resolved. There is sth wrong with my cable and I have bought a new one. Noe everything is going well.
Hi I'm getting the USB Not Recognized / Malfunctioned error messages in Win7 Ultimate. My phone used to connect to my PC flawlessly.
I'm using the stock USB cable that came with the phone, I've tried for weeks now to get it to sync. I've tried uninstalling, reinstalling WMDC, edited the permissions for some registry key related to it, I've even tried syncing with bluetooth. It will not work on any Win7 PC (I haven't got the opportunity to try any other OS's). Also it's not just the syncing issues, it wont even show up as a storage device in Windows Explorer.
I've exhausted all options, I've tried 2 usb cables (one from a car charger and the original one), I've tried changing connection mode from Activesync (enhanced on and off), Disk Drive and even Internet Sharing.
The only way the USB has worked is in bootloader was today during bootloader and in magldr 1.12 (USB Flasher and USB Mass Storage), at first I flashed a newer Energy GTX ROM and then WP7.
Zune does not detect the phone nor does Phone Developer Tools.
Please help, I need to get it working again!!
Thankyou.
After I connect to PC, it does nothing. I'd like to copy pics from sd card...
I did installed the drivers..
When you connect you should get something on your notification bar at the top. Drag that down and you should get some usb connection options...mass storage should do the trick. Alternatively you can download motorola drivers on ur pc and use the phone portal.

that's the problem, after i connect it, it does nothing... nothing shows up on notification bar, windows (PC) does nothing, it doesn't recognize it at all.
I did install drivers and restarted he computer...
so I tryed to connect to different PC and it worked right away with no drivers installed. So something's up with my computer, but it does recognize my camera and usb flash drive...
any ideas?
Yea it sounds like you have driver problems with that computer.
All I can think of is to uninstall the drivers, restart, and plug the phone in. I didn't install drovers when I got mine, just plugged the phone in and it installed the drivers for me.

Have you tried different USB ports? Sounds weird but I've seen this happen with a camera once
yea i tried different USB ports, nothing happens.
i also did this - uninstall the drivers, restart, and plug the phone in - still the same problem
Different USB Cable perhaps?
Different USB Cable did not help either
I'm out of ideas..
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 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.

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 .

I can't connect it to PC . I mean , i conncect the usb cable to my phone and my pc ... my phone shows that it is connected to my pc ... but there is nothing happening . I mean the PC doesn;t find the my phone. What should i do. Ty everybody! Sorry for my english
Well,may i know on what OS are you trying to establish USB connection? WM/Android?...For WM, have you installed windows mobile device center on your PC and tried syncing? As for android,try installing the right version of HTC Sync on your PC. Also, ensure you tick 'USB Debugging' under Settings-Applications-Development. For a few android builds, there will be a notification, prompting you to turn on USB Storage after you connect the USB cable. You have to try all those first before moving on to advanced troubleshooting like manual driver installation,android sdk,hard rest,etc.
