Hello,
I added a USB 2.0 PCI card to an older PC to accomodate
a new Canon USB 2.0 inkjet printer.
The card installed fine and is working, but here's the
problem. All it takes is for the printer to be turned on,
and the PC becomes very slugginsh.
Running HDtach shows about 40mbps (on an Ultra66
Promise controller) while it runs at 58mbps when the
printer is turned off.
Why would the USB device cripple the PC?
I've been in the BIOS to see if there's anything, but
for now all I did is disable the legacy (onboard) 1.1
USB controller.
Any thoughts appreciated.
