Public bug reported:
Hi,
when I try to use my Gembird USB-Keyboard on a machine with a VIA
chipset the uhci_hcd module seems to be unable to set up the device
correctly. Unloading ehci_hcd or using noapic as suggested in some
forums didn't bring any effects.
Dmesg | grep usb says:

00:10.1 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1

This happens on all my VIA machines after grub is booting the kernel, on
my notebook (using ohci_hcd) the keyboard is working fine.
I've tested this issue with all currently supported Ubuntu versions,
Jaunty and 2.6.29 vanilla included. Then I booted from an old Ubuntu
5.10 Breezy Badger Live DVD, where it is working fine too.
Thanks in advance.
