Bug Description
Binary package hint: kvm
Attempts to use -usbdevice host:vvvv:pppp fail with "Warning: could not add USB device host:vvvv:pppp". This is because KVM and QEMU attempt to access them via the obsolete usbfs (/proc/bus/usb), which is not mounted by default in Ubuntu. mounting it manually with "sudo mount -t usbfs usbfs /proc/bus/usb" gets it working (modulo permission tweaks).
