I can think of at least 2 different ways (there are probably more):
- look at the device in /proc/bus/usb/devices and wait until the
driver is bound to that device "(hid)" will show up as the
driver bound to that interface
- look at the sysfs directory for the hid driver and wait for
the symlink to the device shows up. This should be at
/sys/bus/usb/drivers/hid
Hope this helps,
