KDE won't help if the device is not seen as being present...

Had similar problems with a USB external disk a while back.  Worked with
the FC2 kernel but not with WBEL3 (equivalent to CentOS3).  A kernel
update finally fixed the problem.  Are you up to date with the latest
kernel?  The CentOSplus kernel might be worth a try:

# yum --enablerepo=centosplus update kernel

To state the obvious (but perhaps not one still undergoing Windows
withdrawal :-), you will need to reboot to get the new kernel.

Have rebuilt FC kernels on CentOS to get otherwise unsupported devices
working, but hopefully won't have to go there.

Isn't this fun?  :-(  Too bad it doesn't "just work" [TM]. )-:
