Hi all, I''m trying to access USB devices from a DomU running on Xen3.0.1. The only references I could find on the net are about hiding the USB-controller from Dom-0. But this is not (yet) possible in Xen3. Is there a way of passing USB-devices directly on to a DomU? I tried enabling ''host USB'' in the kernel config, but this always results in a kernel-panic during boot. (Before init comes up) Anyone has any ideas on how to do this? (If possible, that is) Many thanks, Joost _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

What I''m looking for is support for USB printers, scanners and webcams. And unfortunately none of these work as a block device. I am currently using a seperate machine as the printer-server, but the whole idea of using Xen was to end up with only one server instead of a collection. (the missus isn''t too pleased about all the hardware ;) ) Thanks about the 3.0.2, I''ll look out for that one. -- Joost _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
