RE: USB PORTS
> My usb ports are not recognizing any usb devices,
I had the same problem. In my case the files usbstore.inf and usbstore.pnf
were missing in my \windows\inf directory.
I made a subdirectory in \windows\inf called usbstorage. I copyed this two
files from a XP machine and also COPYED usbstore.sys from
\windows\system32\drivers (thus the vista version)
After this I plugged in my MP3 player and it worked!! Also my navigation
device and my foto camera.
If you're also missing this two files, try this.
