Best guess offhand, the device needs a .reset_resume function wired
up. Here's what fixed up mceusb devices:

commit 1ad74b6503092097e8eaf014769e6ec9aba29eee

    lirc_mceusb: wire up .reset_resume

    makes driver functional after suspend/resume when woken up via a
    button press on the remote. From Eloy Paris on the lirc list.

Worth looking to see if your device needs similar.
