Description of problem: 
I have a Logitech Navigator keyboard with 
an embedded mouse wheel (the keyboard is 
really *two* USB devices hooked together). 
 
There appears to be a race condition in the 
usbhid module because very often the keyboard 
doesn't get detected at boot time (see dmesg 
output in "Actual Results"). 
 
I can usually fix this by hooking a PS2 kbd 
and typing "rmmod usbhid; modprobe usbhid". 
Sometimes I need to do this twice or even 
three times.  When the keyboard works, I get 
the dmesg output shown in "Expected Results" 
(see below). 
 
I sometimes successfully recovered also by 
unplugging and re-plugging the keyboard, but 
this trick appears to have stopped working 
with the latest kernels. 
 
The first time I've seen this bug is when 
I switched my motherboard to an Abit AN7 
(nForce2 chipset).  I was probably using 
kernel 2.6.1 or 2.6.2 at the time, so it's 
not a new bug. 
 
 
Version-Release number of selected component (if applicable): 
kernel-2.6.7-1.494 
 
How reproducible: 
Sometimes 
 
Steps to Reproduce: 
1.Boot with USB keyboard connected
