I have a Matshita DVD-RAM UJ-840S in a portable caddy. This works just fine with XP, Vista and Windows 7 32 and 64bit. Using Ubuntu 10.10 and also 10.04LTS the drive is detected, but just becomes busy when a CD or DVD is put in it.
I do not believe it is the cable, having tried at least half a dozen.
