kern/46736: Kernel Error with USB possibly OHCI related
>Synopsis: Keyboard and/or mouse do not work with UHCI and OHCI enabled,
>mouse still does not work with OHCI

>Release: NetBSD 6.99.10
System: NetBSD phantom 6.99.10 NetBSD 6.99.10 (DOUGZTR) #0: Tue Jul 24 00:22:20
EDT 2012 doug@phantom:/usr/src/src/sys/arch/amd64/compile/DOUGZTR amd64
On running the install cd, and after booting neither the keyboard or
mouse work. A workaround is to unplug and replug them which
will make them active, however then messages will keep respawning on
the console about device disconnected/reattached. I have tried
compiling a kernel with UHCI disabled but the behavior is still the
same, so it would seem to be an issue with the OHCI kernel driver.
A further workaround is to connect the mouse and keyboard to a passive
hub which for some reason enables them by default, and finally
the hub can be connected to a switch to manually reset the mouse and
keyboard. This is a very serious problem and will cause many to
quit a NetBSD installation from frustration, like I did many times
until I found the little trick.
Boot up a computer with an AMD chipset that uses the OHCI USB driver.
See above, workaround involves using a hub, switch, or replugging the
devices. No known kernel patch yet.
