There was a similar thread here before about USB and suspend. Check that for specifics if in a hurry. Not at computer now to find the earlier email.

Apart from kernel level USB suspend. There are settings in /sys/.... where you can disable USB suspend on a per-device level.

I would assume Fedora disables that for keyboards and mice (think previous thread was about mice getting forgotten) when detected as such.
