Well unfortunately I know about the via problem. This is a IBM Thinkpad 770X
and has an
Intel processor and the Universal Host Controller entry under system is
Intel 82371AB/EB
PCI to USB.

The device I am using works perfectly when I have it plugged straight into
the USB port on
the system. It always fails when I have the hub plugged.

I have uninstalled and re-installed all drivers and noted the following
stange thing happening:

Uninstall drivers for webcam then reboot, then plug webcam -> drivers are
installed for webcam then reboot

Uninstall drivers for HUB, reboot then plug HUB --> drivers are installed
for hub, reboot

Now boot up with HUB only and then plug webcam  in -> it installs drivers
again!

Why does it do this? Does this give a clue?

I am at a loss now.
