USB Mass Storage Device Not Recognised - DVD RW

[Guest]

I have an USB2 external enclosure for a CD-RW which has worked flawlessly. I
recently installed a DVD-RW (Samsung 16x TS-H552B) and Windows XP SP2 won't
ackwowledge it at all. If I put the CD-RW back in then presto it works fine.
Back to DVD no action. I have tried upgrading all drivers,
unloading,reloading and nothing works. The Disk Manager doesnt show it. All
the lights on the front are fine and the tray opens and shut from the front
panel. It is also plugged into a Dell notebook via a USB2 Carbus adaptor
which works fine but I have also plugged the DVD directly into a USB 1 port
with no luck. I also tried it on a Win2000 notebook with the same problems.

Is the external enclosure incompatible with a DVD -RW?

Can anyone help?

USB Hub Power Management - disable : Start/run, type DEVMGMT.MSC , then
rightclick each USB Hub device, Properties, uncheck the box on the Power
Management tab.

Thanks for the suggestion. I tried that - turned off the Windows Power
Management ability to power off device check box but that didn't help. I
suspect that it is something to do with the external enclosure as it works
with the older CD-RW. Or is it something to do with Windows thinking that
the enclosure is for the CD-RW and then won't recognise the DVD-RW? When I
uninstall the drivers it re-discovers the CD-RW again and the USB Mass
Storage Device. I've been reading a lot about SP2 having problems with USB?
This should have been a straight forward swapping a CD-RW for a DVD-RW!

Hi Sam:

I had the same issue with an external Sony DVD-burner, it was working fine
and all of the sudden it stop and Windows doesn't recognized it. Did you
find a solution for this?

Thanks,
