Help usb port problem

hi

I have a big problem with my samsung galaxy s. After i did the update to android 2.3.3 , I was unable to connnect the phone to the pc. When I connect the phone to the pc it displays unknow device.

I already uninstalled and installed the drivers on my pc, tried with 2 different usb cables, tried also on 3 different pc's but nothings work :(

yesterday I plugged it in my pc and it worked for like 30 seconds. afterwards the connection broke up and the pc displayed unknown device detected.

Does somebody have a sollution or the same problem ??

I looked on many forum but there wasn't a thread of this kind...

thanx joris
