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 I've withdrawn the previous patch and created patches for kvm and qemu that use /dev/bus/usb/ and attached the debdiffs for Hardy and Gutsy-proposed here. ** Attachment added: "kvm -4ubuntu3 gutsy-proposed debdiff" http://launchpadlibrarian.net/10207748/kvm_28-4ubuntu3-gutsy.debdiff -- Could not open /proc/bus/usb/devices https://bugs.launchpad.net/bugs/156085 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
