Hi!
After reading some posts in this list I realize there are quite some
problems with the VIA pci chips. I have one of those cards and i'm
trying to get it working. Hopefully my debug output might be of some
use to resolve this problem.
The card has two usb 2.0 ports.
# lspci -vv
***This is just the integrated usb 1.0 ports (2of them), they are
working fine*******

Both the ports on the cards are connected to Hi-Speed usb devices (two
umass devices, one ipod and one external LaCiE harddrive). It seems
the port powerup correct, as the ipod starts charging.
Ideas and responses appriciated :=)
Cheers
