Hi,
I get a warning in the domU kernels when I pass-through the ehcu/uhci
devices. The usb-ports seem to work. I can use usb-sticks and a sundtek
DVB-C stick. A microsoft usb-mouse is not recognized.
Can I ignore the warning or do I have some serious issue/misconfiguration?

By the way, when I attach all the uhci/ehci devices to one DomU the
error occurs only on detection of the first ehci device.

You can ignore it. There is a patch for 3.2 to remove this.
