Hi there. I have just recently started trying to use the USB device on
my laptop and recompiled my kernel with the following pertinent options
for USB itself....
device ohci # OHCI PCI->USB interface
device usb # USB Bus (required)
device ugen # Generic
device umass # Disks/Mass storage - Requires scbus and da
and the following options for SCSI (I'm using a USB zip drive)....
device scbus # SCSI bus (required)
device da # Direct Access (disks)
Now, I recompiled, installed, etc., and rebooted. Voila, I was able to
use my USB zip drive (which is incredibly fast, btw), and all was good.
I have two questions. First, when I had the Zip drive connected, I
tried to start X and had two problems. First, my mouse simply would not
work, and secondly, the whole system was much slower than it normally
is. I didn't notice this until I started X. I realize that most
probably, this is an IRQ conflict between the zip drive and my laptop
mouse (?) but I've not investigated further.
My second problem is that since I put the USB options in my new kernel
(and use it without actually having any USB devices attached), I get the
following message from the kernel all day....
usb0: scheduling overrun
usb0: scheduling overrun
usb0: scheduling overrun
usb0: scheduling overrun

It doesn't seem like it's hurting anything, but I'm just curious--
a) what does this mean, and
b) what can I do to fix it?
Also, anybody experience any oddities when using a USB device and
then trying to use a PS/2 mouse?
