>Description:
I installed FreeBSD 4.1-release on this machine (from WC CDs) correctly, and
immediately after recompiling kernel it viewed fine my Logitech Pilot Wheel
USB Mouse. It was real plug'n'play too (using /etc/usbd.conf). All fine.
(I used it also on a precedent K6-400 machine with 4.1-S)
After cvsupping to 4.2-stable and recompiling all enabling SMP support in
kernel I noted that USB mouse stopped working.
I tried recompiling just a kernel without SMP options and the mouse resumed
normal operation.
I booted many times using SMP kernel and non-SMP kernel, every time the
behavior of USB was reproduced.
So I think there are some problems with USB code when running in SMP
kernels.
Plugging the mouse in the USB port under SMP kernel caused also interval
console messages from usbd about resetting the usb ports itself (I guess
it's something about retrying handshaking or similar).
>How-To-Repeat:
Use a SMP kernel and some USB device (to be honest I tried with
mouse only, till now)
>Fix:
use a non-SMP kernel
