HID devices won’t go to sleep when the computer does, else they couldn’t wake it back up.  (Keyboard & mouse, mainly.)

The two audio interfaces may or may not sleep.  Try checking their indicator LEDs when the computer goes to sleep: I’d expect them to visibly show that they’ve gone to sleep if they do.  If they do, then on wake, they *could* do this sort of thing.

I’d go after the RAID enclosure first, particularly if it’s hardware RAID, since that means it’s “clever,” thus suspect.  Check that you’ve got the current firmware:


If it’s one of their JBOD models, requiring that you do some sort of software RAID, I’d expect a much different report in the kernel log if the corresponding software RAID component had a bug, which would mean it’s got some fundamental USB compatibility problem if that’s the device causing the problem. Again, check for firmware updates.
