Running XP Pro sp3 or sp2 plugging in a WD-Book 500Gb USB 2 drive to any port results in very slow transfers.
It takes 10mins per gigabyte typically. On a similarly set up desktop system the drive runs at 1min 40secs per gigabyte.
I can find no reference in the Bios to usb.
The system has two XP partitions and they both react the same, even immediately Windows finishes installing.
The system says it has NEC enhanced usb. The drivers are the same on both systems. So far I can only think it is hardware in that all ports are probably one chip and it is running at 1.1 speed.
I do not get any messages.
Anything that tells me it is not hardware would be very greatfully received.
