Hello! I've posted this several times, but with no success. I have an external AOPEN CD-RW with USB interface, it works fine with 4.10, but doesn't work with 5.ANY (including 5.3BETA7). 5.x DOES see umass device, but doesn't see any cd device Kernel is GENERIC, I repeat, GENERIC. Flash disk works fine. USB system is functional. -- Alex.
