Same with:

acd1: <ASUS DRW-0402P/D/1.05> DVDR drive at ata1 as slave
acd1: read 5511KB/s (5511KB/s) write 2755KB/s (2755KB/s), 2000KB buffer, PIO4
acd1: Reads: CDR, CDRW, CDDA stream, DVDROM, DVDR, packet
acd1: Writes: CDR, CDRW, DVDR, test write, burnproof
acd1: Audio: play, 256 volume levels
acd1: Mechanism: ejectable tray, unlocked
acd1: Medium: no/blank disc

I simply use it through ATAPICAM layer with cdrecord - always
worked perfectly.

Would be interesting to know why these devices don't behave properly.
