Hi, there was a thread about problems with the LG GSA 4040-B dvd-writer in an extermal USB 2.0 case from Genesys Logic, Inc. a few days ago. I have the same combination and the same problems and tried the second patch from the thread with 2.6.0-test11. It works way better than before, but if I copy large amounts of data (>70MB or so) from the dvd to the harddisk I get I/O errors (see attached dmesg). DVD+RW writing seems to work though, but DVD-R(W) does not.
Thanks a lot, -cornelius
