What about /dev/bus/usb - it supports inotify fine on udev?
Yes it should since it's a regular filesystem.
I was thinking of this too since /proc/bus/usb is deprecated in favor of
/dev/bus/usb. If someone was willing to port QEMU to /dev/bus/usb, it
would be greatly appreciated!

Now inotify based solution probably won't be pretty because we'd have to
monitor each subdir. ie When new device get added top level /dev/bus/usb is
not modified, what does get modified is /dev/bus/usb/<bus_num>/ directory so
we'd have to monitor /dev/bus/usb and dynamically register/unregister monitors
for each /dev/bus/usb/<bus_num>/.
Maybe it won't be that bad. If I get a chance I'll give it a shot.
btw Interface to HAL might still be useful in general to monitor other device
classes that we may want to automatically assign to the VMs. So I'll play
around with that too (some day :)).
