o The hacking was 8 months ago when I was getting 2.4.9-ac12 working
for the first time -- my apologies if I'm a little fuzzy about it
now.
o My notes show that I got a patch against se401-0.23 from Jeroen
Vreeken. I think I remember that I had to make some simple change
to get it to compile with the 2.4.9-ac12 tree.
o I'm attaching "0.23p1.diff", which is `diff se401-0.23{,p1}/se401.c`.
Past that, I made some trivial changes to the LED handling, and that's
what I'm using now.

o Yes, it is set. My guess is that I'm having problems because the
hotplug scripts were installed with SuSE 8.0 (kernel 2.4.18), and
I'm booting 2.4.10 on the system.
o More: Since my last post, I got the same USB crash I'd been getting
about once a week on the old RedHat/2.4.9-ac12 system. I posted
about this on 4/1/2002, but didn't get any replies. USB stops
working, and syslog fills up with several gigabytes per hour of:
kernel: [cd108120] link (0d108092) element (0cd6c000)
kernel: 0: [ccd6c000] link (0cd6c030) e0 Stalled CRC/Timeo

o To fix the problem, I wrote watchdog scripts which restart the USB
system when it crashes. In this current thread, I wrote:

o On my new 2.4.10 kernel, the watchdog USB restarter failed. The
only way I got back running was to do the modprobes/insmod with the
webcams unplugged, and then plug them back in. I haven't figured
out how to write a script to do that. :-)
