Hi,

i found my desktop USB no longer functioning after I connect a usb hub to a
usb port connector on the motherboard. Even I remove the usb hub or reset
the cmos/bios settings dosen't help. It seems that no power output from all
the usb ports/usb port connectors. I am sure its hardware related as I have
restored the Windows image and the problem is still there. Anything I can do
now ? My motherboard is Asus P5PL2

thanks in advance
