lsusb gives you a bus number and a device number eg.
Bus 005 Device 002: ID 0463:ffff MGE UPS Systems UPS

what is the resukt of ls -l /dev/bus/usb/<bus number>/<device number>
(for preceding example, I get
crw-rw-r-- 1 root nut 189, 513 Nov  7 20:39 /dev/bus/usb/005/002, and it
is the only device for my UPS).
