Yo Tom and Tim,
1) Tom says that the card drivers override any older OS concerns.
2) I have a homebuilt that has only USB 1.1 support on the system board. I
added a PCI USB 2.0 card along with installing the software that came with
that card.
However, on this machine I also run XP Pro SP2 (which has USB 2.0
support as does SP1).
I was merely speculating about the OP's system which has (if I understand
correctly) NO native HW support for USB 2.0, and the chance that the OP is
also running a Windows OS with NO native SW support for USB 2.0 (pre-XP
SP1).
Tom is saying ( I think ) that the software drivers supporting USB2.0 for
the card will trump the OS not supporting those devices.(The motherboard HW
support is immaterial once the USB 2.0 controller card is added as it
becomes the needed HW support).
