Warren, thanks for the additional info.
I assume that the yottamaster device runs Linux, just like 99% of other such devices. as to whether it uses linux software raid or some cheap (megaraid???) chipset, I don't know, nor know how to tell. but I'll check that URL you sent and see what happens.
Thanks again!
Fred

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:
https://www.yottamaster.com/?route=common/driverIf 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. _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
