Whoa, hang on.  I don't have the problem identified by the original
poster.  I'm just a thread hijacker ::-).

My particular bias against hotplug is two-fold:
	1) It is far more difficult to understand than /etc/rc.d
	2) The only USB device I have is a MIDI interface, which I
just want to leave plugged in.

#1 - sometimes, hotplug doesn't "coldplug" my device properly.  I
don't really know why, and re-plugging the thing in usually works.
I don't understand why they should be different processes.

It's a minor headache that I'd rather just relieve with a shell
script.  Problem is, my Midisport needs firmware loaded.  I need to
make use of hotplug's firmware facilities, since I cannot predict
where in /proc/bus/usb/ the device node will appear.

#2 - I don't need hotplugging!  This is a desktop machine that never
changes.  I have all of one device.  hotplug seems a little like
overkill in my degenerate (but probably very common) case.

Trust me - if I was losing mouse and keyboard, I'd be all over that
kernel upgrade!
