As you mentioned that you didn't change other settings, may I assume

I'm sorry, I missed that. Intel ME was neutralized with me_cleaner.
This is for both my tests with coreboot and with stock BIOS.
Please always retest with fully functional ME firmware.
please send a coreboot log taken with `cbmem -c` (you can find cbmem in
util/cbmem/ in the coreboot source tree).
Here is one with the same coreboot version/build as it was in the dmesg
output in my bug report on the openbsd-bugs ml.
Thanks. I can't find anything suspicious. Though, coreboot doesn't have
to do much for USB controllers anyway.
Some more questions:
o Are the drives you tested all SuperSpeed devices?
o Do the ports work when using the EHCI controller?
(The ports can be switched to either xHCI or EHCI. In Linux you'd
just only load the EHCI driver and not the xHCI one, don't know
about OpenBSD.)
o Did you ever test with another OS?
o Can you provide a dmesg from a run with vendor BIOS?
o Can OpenBSD boot/run without BIOS help? If so, could you test with
a different payload?
