[wplug] error msg for unknown device

[bgtrio at yahoo.com]

This is interesting to me.

I picked up a digital camera (Walmart special- Lexmark printer + Concord 
2 megapixel camera for $110, and the box claims it supports Redhat, Suse, 
etc.).

However, the package lies and the camera isn't officially supported 
(although the printer is with binary only drivers).  But fortunately for 
me you can mount it as a mass storage device, on my Redhat 8.0 system it 
shows up as /dev/sda1, just like Alexandros'.

But sometimes it complains about bogus sectors or says there are too many 
FAT tables to mount it correctly.

Here's the crazy part- I seem to be able to fix it by running 

cdrecord --scanbus

once or twice.  I discovered this accidentally when I was surprised to see 
my non-working camera appear in the list of available scsi devices on my 
computer, and whenever I have mounting problems cdrecord --scanbus seems 
to clear them right up and mounting works fine.

I suspect that this command does something to reset the scsi device 
drivers, but I haven't the foggiest idea what.  Perhaps someone wiser than 
me has an idea?

Anyway, the camera and printer were a good deal once I got them working :)
