This thread seems to have gotten a little off track from the original subject header.
The issue has not been the identification of the USB ports themselves, per se, but in fact the identification of devices attached to USB ports ... the USB ports appear as "working" in Windows, however any device attached to the port is not recognised. This is a differnt issue from some of the above responses.
Seems to be a "trait" of 5xxx model ACER lap[tops. Althpoigh I posted my solutions above, it ahse happened to my ACER 5100 laptop again. This time, my previous solution failed miseably. The USB ports appears as funtioning in the Windows Device Manager - i.e. there is nothing wrong with the ports themselves. However, as soon as any device is attached (mouse/keyboard, w/less mouse/keyboard, USB stick, USB external HDD, et al), the error message appears that the device is not recognised.
Temp solution has been to use a USB port PCMCIA card - works sometimes, fails others.
