My question is this: After backing up the scripts I have changed in

Yes, updating to lfs-bootscripts-3.2.2, udev-058 and the newer udev
rules file should be safe enough to do. udev-059 was recently
released, though it included major changes which we haven't been able
to assess the affects of yet, so I'd strongly suggest you stick with
udev-058 for now.
Thanks, Matt. Updated to the 3.2.2 bootscripts and the udev -058. I
know have 100% printer reliability. Haven't had a chance yet to try the
camera.
In LFS what is the sequence of events that starts on a hotplug event?
Just for sake of argument let's say I turn on my printer. After reading
quite a bit of stuff about udev and hotplug, I'm confused. It's
entirely possible that I'm being really dense here, but let me quote
from the man pages--it's a summary of what goes on:
UDEVSEND: udevd receives the events from udevsend which is called by
hotplug(8)
HOTPLUG (8): [Some stuff about what hotplug does] The hotplug program
path name is registered in /proc/sys/kernel/hotplug, and normally holds
the value /sbin/hotplug. [Stuff about agents and cold-plugging]
Here's my take on what happens: Printer on---hoplug calls
udevsend---udevsend starts udevd. I know that's oversimplified. The
reason I'm asking is that both before AND after I upgraded 'cat
/proc/sys/kernel/hotplug' gives me '/sbin/udevsend'. I would appreciate
it if someone could point me to a document that contains of sequence of
events or just lay it out here.
Thanks,
Dan
