Hello Fausto, I found that this was caused by the READ DISC INFO command. This command is required only on CD-R/RW devices, which we're not emulating, so rather than try to fi it, I removed support for this command, returning an ILLEGAL REQUEST sense code instead. I've updated it in CVS as well. Camiel. On Feb 18, 2008 1:30 PM, Camiel Vanderhoeven <iam...@gm...> wrote: > Hi Fausto, > > Yes, I did update the code in CVS.
