The backend ID is typically a sysfs path or USB platform ID -- the latter working well for USB devices, but not working for devices with autoincrementing values (e.g. hidraw) or random values (e.g. bluetooth), for example:
/sys/devices/0000:00:14.0/usb1/1-3/1-3:1.1/0003:03F0:6841.010E/hidraw/hidraw6
Just use the device ID instead, as that's already made up of the physical and logical IDs combined, which is exactly what we want to use for identification.
Fixes #7095
