More data. Progress has been made, but questions remain:

When I plug in my Canon LiDE 30 USB scanner and fire up Xsane, it 
announces that it cannot find a scanner.  However, if I leave it plugged 
in, logout, and log back in, then Xsane finds the scanner and every 
thing works swimmingly.   Under FC3  it does not seem to matter.  Hot 
plugging the scanner works fine.

Can anyone shed light on why the "hot plug" capability is not working 
for FC5?  I did notice the "hot plug" scripts are gone but I assumed 
that was because UDEV (or HAL, or something else) was suppose to take 
care of this.

Any assistance or enlightenment would be appreciated.

Thank you,
