[Xen-devel] pciback for usb-controller and usb-storage on x86_64 ends in Oops

[Patrick Scharrenberg <pittipatti@xxxxxx>]

Hi!

I tried to pcipassthrough usb-controllers to domu to use it with a
memory-stick.

First xen complained that the driver needs write-access to its
configuration space, so I added these to pci-quirks.
Since it still didn't work I also added the device to pci-permissive but
I still get an errormessage with Oops (at the end of this email) when
sticking in the memory-stick.

I tried xen-3.0.3 and latest unstable (12053:874cc0ff214d).
I use the fedora 2.6.18.1-xen0 since otherwise my sata-controller is not
detected.

What can I do?

Patrick
