Unfortunately anything you've learned about hotplug is now obsolete,
because Dapper replaces hotplug with udev.

So you need to go to /etc/udev/rules.d and look for your scanner.
On my Dapper system, the scanners are all in 45-libsane.rules.
You'll see a bunch of lines like:

# Epson Corp.|Perfection 2400 Photo
SYSFS{idVendor}=="04b8", SYSFS{idProduct}=="011b", MODE="664", GROUP="scanner"

(that's my scanner). The MODE="664" is how the scanner gets set to
be group-writable when it gets plugged in. But I don't see any
Epsons numbered 4800, so there's apparently no entry for your scanner.

If you can find out the vendor and product IDs your scanner reports
when you plug it in (lsusb should tell you that, or usbview if you
prefer your USB IDs all gooey) you can make a line for it there.
(And if it works, file a bug asking for your line to be included,
of course.)

Wouldn't it be nice if they actually wrote documentation for this
stuff when they yanked old working systems out and replaced them
with brand new systems? But in any case, don't waste your time
looking for the nonexistent sekkrit hotplug documentation, when
what you need is the nonexistent sekkrit udev documentation.
