I have a PCMCIA USB2 Cardbus. It was recognised by my laptop (XP Pro SP2)
but no power was given out. i.e. when plugging optical mouse into card no
light was seen. After a few minutes, or less, the computer freezes. No mouse
or keyboard use. Have to reboot by turning off computer. The card has worked
on another identical laptop. I can find no cause from the log files. Any
suggestions please.
