Hello, Everyone
I am still having the problem that is referred to in the above quoted message, 
and in the logs that are quoted in that message.  I have two USB2 busses on 
our Abit KD7 mainboard.  A cable goes from one of them to two ports on the 
front of our machine.  Another cable goes to two ports on the back of our 
machine.  Right now, our CD burner (Iomega 52X external, USB2) has 
dissappeared (it is connected to a port on the back of our machine.  There 
only appear to be issues with the ports on the back.)  If I rebooted, it 
would reappear.  If I took the cable from the burner and put it in one of the 
open ports on the front of our machine, it would reappear immediately.  If I 
left it in the front, it would not dissappear anymore.  In a minute, I'm 
going to try a new experiment: I'm going to unplug the burner and leave it 
unplugged for a few minutes, leave the machine alone, and then come back and 
plug it in the same port that it dissaapeared from.  If that doesn't bring 
back the burner, then I will try the same experiemt, but I will replug it in 
the other port in the back.
I'm sure someone has already had the thought, "Maybe your burner is bad."  
Good question, but I have had our only other USB2 device (EPSON Perfection 
2400 Photo) dissappear while connected to one of the back ports.  Basically, 
I've had it happen that whatever I have connected in the back will dissappear 
eventually, but if I plug back in immediately in one of the front ports, it 
will come back.  Like I said earlier, if I leave any of the "dissappeared" 
devices connected to a back port and Reboot, it will reappear.  This makes me 
at least _Suspect_ that this might not be a pure hardware issue.

Anyway, I will get back to you with the results of my experiment.

P.S.: To add insult to injury, I checked the same log files that I quoted from 
above.  Now they have no reference whatsoever 
to /media/cdrecorder, /dev/scd0, hotplug, fstab-sync....
