Comment 7 for bug 156085

Scott, thanks for the explanation. When I'd re-aimed kvm at /sys/bus/usb/ I hadn't realised that it looks a for a file 'devices'. I thought it was looking for the base of a directory-tree containing the devices, which is what /sys/bus/usb/devices is.

I'm not sure who is primary maintainer at Ubuntu - several people are listed as adding patches, and it's a MOTU package. I'm an end-user that wants the fix.
I've withdrawn the previous patch and created patches for kvm and qemu that use /dev/bus/usb/ and attached the debdiffs for Hardy and Gutsy-proposed here.
