NeroLinux 2.0 "losing" USB DVD RW drive Fedora Core 3

I have a Plextor PX-716UF external DVD burner. I’m running Nero Linux 2.0 on Fedora Core 3. Most of the time, it works great.

Occasionally though, when I load up NeroLinux, Nero won’t find the Burner. It only shows the internal DVD-ROM and cdrecorder.

I still see /dev/sg0.

Reboot fixes the problem though.

Any ideas as to what’s going on?

EDIT: well, I unplugged the USB drive and reconnected it. Now, i have no /dev/sg*.

I’ve tried running modprobe sg with no luck. Rebooting is the only thing that fixes this.
