Your initial comment made me smile - it was the first thing I tried. When I realised that wouldn't work I got smarter and did
mount --bind /sys/bus/usb /proc/bus/usb and felt mighty pleased it worked! However qmeu/kvm still couldn't find any devices and I realised it was because in /sys/bus/usb/devices all the device-links are relative, and begin ../../../devices Unfortunately, in the /proc/bus/usb tree that takes us to /proc/devices which is a regular file and already exists - drat, foiled again! If other's can confirm this is a problem on 32-bit and 64-bit qemu and kvm I'll post apply the patch and post an SRU debdiff. ** Changed in: qemu (Ubuntu) Importance: Undecided => Low Assignee: (unassigned) => TJ (intuitivenipple) Status: New => In Progress ** Changed in: kvm (Ubuntu) Importance: Undecided => Low Assignee: (unassigned) => TJ (intuitivenipple) Status: New => In Progress -- 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
