I made sure not to copy either the /sys or the /proc, but just to
create those directories. Should I not even be creating the /sys
mountpoint??! I'll try removing it when I get home tonight, then
reboot. Grasping at straws....

Thanks,

No, the /sys and /proc directories must exist, to be used as mountpoints.

Is lspci showing your usb Controllers?

Right... that's what I thought. [OT: A friend reported that, under
mandriva
2008, the /sys on his unmounted partition was minimally populated?
Seems strange....]

Yes.

I tried adding "service usb start" in rc.sysinit right before udev is
started. It did load the usb modules, but there were *still* no
/dev/sd* devices created. So you plug in a thumb-drive, it lights up,
but no way to access it. Fortunately, it *seems* that the drive which
was showing the errors has settled down. May have just been too cold
from sitting out in the Montana weather, although I did let it warm up
for 12 hours after bringing it in to the house. I will keep this setup
intact in case anybody has an idea of what is going on, since this is
so strange.

Thanks,

Scott.

Had to look back to your original post. 2006 is a very old version. :)
In 2008.0, there is no /etc/rc.d/init.d/usb. It's all handled by udev
and /etc/rc.d/rc.sysinit.

Anyway, try adding the usbcore, usb_storage, and scsi_mod to
/etc/modprobe.preload. Those are the modules used in 2008.0. I'm
assuming they were the same in 2006.

Also, try changing the udev logging in /etc/udev/udev.conf
to debug.

Well, the machine this one is intended to replace is still running
7.1, so I guess age is a relative thing.... ;)

Yeah, that's how it is supposed to happen in 2006 too. Dunno why they
left the init.d/usb lying around.

Okay, tried all of that, with no luck. I notice that it doesn't
mention "debug" in the udev.conf file comment, as it does in 2007 and
2008? Where would I be looking for debug output? I don't see any udev
lines in the log files I looked at: messages, syslog, all of the logs
under /var/log/daemons.... In fact an rgrep there found nothing for
udev on the buggy system.

Thanks,
