I'm running tmk core with on my ErgoDox keyboard using the code from https://github.com/cub-uanic/tmk_keyboard, the repository with my code (and tmk_core cloned to tmk/core) can be found here: https://github.com/fd0/ergodox-tmk

I've tried to get USB wakeup working by pressing a button on the keyboard. So I enabled USB wakeup in the BIOS and OS (Linux), but now I'm unable to suspend: Wakeup is instantly triggered on suspend, as long as the keyboard is plugged in.

Any idea on what's going on here or how to debug this? Did I configure something wrong?
