Resetting the SCSI bus on UDB???

Does anyone know how I can reset the SCSI bus on the UDB without
rebooting? I finally got my CD-ROM working (it needed a good active
terminator) but once I unmount and remove a CD from the drive, I always
get a CD-ROM I/O error after trying to mount it again.

It seems I need to somehow ``reset'' the SCSI chain so that the host
adaptor will ``find'' the CD-ROM again. I'm not sure why this is
occuring, but I recall an echo command will do the trick when directed
to /proc/scsi. I just don't remeber the details. Anyone else have these
problems with a CD-ROM drive? Also, I have to keep a disc in the drive
to spin up when I boot. Weird.
