External hard drive stops and starts on USB2

  snapscan 12:31 23 Apr 06

Have Freecom 250GB usb 2 External Hard Drive with separate power supply which when connected to a usb2 port keeps starting and stopping.
If I connect it to a usb1 hub it works slowly but ok. I also get the message that I should connect it to a faster available port.
Connecting it to a faster port brings me back to the original problem
I am using xp with service pack 2
The MB is an ASUS 4C800-E deluxe
I have tried a Seagate 300gb usb2/firewire which works ok on firewire but has the same problem on usb2
Could this mean that it is xp or the MB.
There is nothing on the ASUS site
Microsoft has a couple of KB answers but not exactly the same problem as I have.
Anyone any ideas
