Intelligent Stick USB Memory Device Problem

My daughter has a PQI (I think!) USB "Intelligent Stick" 64 mb Memory
device - basically an external pen memory - for school use. I cannot get
Windows XP to recognise this, despite downloading the driver from the PQI
site, and asking Windows to scan for it. In theory it should simply
recognise it as an external storage device in My Computer, but it does not.

Any suggestions??

Thanks in advance.
