I have a problem on NetBSD 4.0_STABLE with USB ports on an Intel
DG33FB motherboard not working under certain conditions.
If I follow the following steps the hard-wired rear (mounted on the
motherboard) ports will fail to detect the insertion of a USB flash
drive:
- boot the box cold (a warm reboot never reproduces the problem)
- boot with a USB mouse plugged in on one of the rear ports (with no
mouse or just a PS/2 mouse the problem cannot be reproduced)
After a matter of seconds (maybe 5-10 seconds?) after having reached
the login prompt I'll see the log:
uhub2: device problem, disabling port 2
Any device plugged into one of the rear ports will now not get
detected. I can still plug my USB flash drive into one of the ports
plugged into the internal USB headers and it works fine. I've
reproduced this on 2 Intel DG33FB's. (Btw, the same procedure does not
show any problem when booting into Windows XP).
If I change it round a bit and plug the USB mouse into a port
connected to one of the internal USB headers, the other port on that
header will not work but the rear ports will.
I'll try and compile with USB_DEBUG and repeat the procedure.
