Attempted to expand one of the two usb ports on my XP desktop. (Both work.)
Connected a DVD player, a flash drive, a camera and left one port empty. None of the devices worked. The DVD player registered as an unknown device. The other ports registered as unused.

Plug in hub.
System tray pops up a balloon "unknown device"
I 'think' it has something to do with xp service pack 3! No solution but certainly looking.
Note: USB unrecognized.
Of course this happened after installing service pack 3!
Nothing hooked up to this hub works. It passes through nothing.
my pc stop the hardwere while i am bussy with any usb device
