The burner works great with 2.6.9-rc2, I burned 3 times usind dummy mode, and I burned 2 CDs, everything was great, I'll buy more blanks and a rewritable CD tomorrow and do a more intensive test ;) But, When I unplug the USB cable or turn the drive of, I get a kernel oops: Sep 15 23:34:55 localhost kernel: usb 1-2: new high speed USB device using address 2 Sep 15 23:34:56 localhost kernel: Initializing USB Mass Storage driver...
