How to get /media/cdrecorder to reappear without rebooting

[Steven P. Ulrick]

Hello, Everyone :)
I am continuing to have the problem that is referred to in the following 
message from this list:
http://www.redhat.com/archives/fedora-list/2004-December/msg06690.html 

Of course I would love to have some insight into what is actually causing my 
external, USB 2 CD burner to dissappear for reasons that I know not of.  But 
the purpose of this thread is to find out if there is a way I can reset 
something so that I can get my cdburner back without rebooting.

Also, here are the latest references to this issue from /var/log/messages:

If anyone can help me track down where this problem is located, I would be 
glad to report any bugs that need to be reported.

Have a Great Day,
