triggerhappy devices lost after resuming from suspend

I'm finding that I need to restart the triggerhappy daemon when resuming from a suspend in Linux.

System: Debian/stretch
triggerhappy package version: 0.5.0-1
Linux kernel:  Linux salsa 4.11.0-0.bpo.1-amd64 #1 SMP Debian 4.11.6-1~bpo9+1 (2017-07-09) x86_64 GNU/Linux

The device giving me a problem is a Griffin powermate, which is a rotary encoder I use for volume control.
