Just FYI, I've upgraded to 5.8 and the problem is still there :[

Description: I've just upgraded my Dell Latitude E5530 from OpenBSD 5.6 to 5.7,
and used M:Tier's openup to get latest binpatches.
As soon as I plug a device into the left or back female USB adapter, the system
totally freezes (only solution is to press powerdown button for 10 seconds.
Removing USB device, trying to switch to another tty, etc. do not unfreeze the
system). If I plug a USB stick in the right female USB adapter, everything
seems OK.
I assume the problem is that left & back female USB adapters are linked to the
internal USB 3.0 hub whereas the right female USB adapter would be USB 2.0.
NOTE: apparently, the problem existed in 5.6: twice, I got a freeze just by pluging
in a USB device in the left female USB adapter. Since I did not use OpenBSD
(5.5&5.6) for a long time on this computer, I did no deep testing of the
problem under 5.6 and directly upgraded, thinking this would solve the problem.
The dmesg attached it the one after freshboot + pluging of a USB stick in the
right (USB 2.0?) female adapter. I have currently no idea on how to get more
information about the problem, since system is totally froozen, not crashed.
How-To-Repeat:
Get a Dell Latitude E5530 running Open57 and just insert a USB stick
into left/back USB female plug
Fix:
nothing found to solve the problem
Could you try a -current snapshot? A bug causing the same symptoms has
been fixed, so I'd like to know if this is another issue or not.
