I have tried it more or less successfully. I purchased a usb2 card
which uses 3 interrupt lines, and my motherboard usb1 ports use
another. My problem was one of the usb2 interrupts tried to share with
my modem, and the modem would not share it. After printing out the
report and studying it, I learned the sorting of the interrupt lines on
each pci slot, and was able to rearrange my pci cards around to get two
of the three usb card ports to work. There are two OHCI ports and one
EHCI port. By using one command in config.sys for ohci, it keeps the
second ohci port inactive which is on the same line as the modem,
therefore the modem works and I can use all the other usb ports. And by
putting a powered hub on the EHCI port, I have great access to it.
