There are lots of things you can do sir.
I tried all 6 usb port on my pc, tried with 3 different cables (2 samsung, 1 logitech, all working on my sgs2). i tried in a different pc too.
I cleaned the micro usb port with alcool and now is cleaner than when i bought it. one cables was new from original galaxy box.
I tried every driver found on xda (4 different version of this usb driver, a specific one for 64bit, kies driver). i tried to plug in another i9000 that installed is own drivers in debugging mode and worked perfectly, but mine is still unrecognized
unfortunately phone is updated to 2.3.3 and gingerbreak doesn't work
Suggest me other ideas and i'll try....
