Package: linux-image-2.6.18-5-xen-amd64
Version: 2.6.18.dfsg.1-13etch4
Severity: normal

I have exported (or whatever you call it) all USB ports on my XEN server
to one of the domU instances. I've been using an USB connected printer
for some time without problems.
However, today I plugged in an USB CD writer. And the oops below came
out with the writer unusable.

And the XEN is 3.0.3 from etch. From dpkg:
