try installing/updating KIES on your computer. Disable USB debugging from phone settings. then try connecting again. Launch KIES and see if the device is recognized. You havent mentioned if you made any changes on the phone from Stock ROM.

Also check windows update...for any driver downloads

At least you could tell us that you solved your problem

First make sure you have proper drivers installed

install PDAnet and select samung. Now connect your s2

if it still doesnt install the drivers, its the fault in the computer because if it says usb device not recognised, then its his fault

try in the backside usb ports --> worked for me one

or power off your PC and remove the plug and wait for five seconds and then turn it on (im mean power it on )

now you should be able to connect your device
