This looks like the entire unusual_devs entry is not needed. Can you send a copy of your /proc/bus/usb/devices file with the drive plugged in? > scsi2 : SCSI emulation for USB Mass Storage devices > Vendor: MITSUMI Model: CR-4802TE Rev: 2145 > Type: CD-ROM ANSI SCSI revision: 02 > sr0: CDROM (ioctl) error, command: 0x46 00 00 28 00 00 00 00 10 00 > sr: sense = 0 0 > Non-extended sense class 0 code 0x0 > Raw sense data:0x00 0x00 0x00 0x00 > sr0: CDROM (ioctl) error, command: 0x46 00 00 20 00 00 00 00 18 00 > sr: sense = 0 0 > Non-extended sense class 0 code 0x0 > Raw sense data:0x00 0x00 0x00 0x00 This looks like your drive doesn't support certain CDROM commands, and it doesn't report back a correct error code either. > sr0: scsi3-mmc drive: 8x/8x writer cd/rw xa/form2 cdda tray > Attached scsi CD-ROM sr0 at scsi2, channel 0, id 0, lun 0 > Attached scsi generic sg0 at scsi2, channel 0, id 0, lun 0, type 5 > USB Mass Storage device found at 6 > > my system: > i686 AMD Athlon(tm) XP 1700+ > gentoo-dev-sources, version 2.6.7-gentoo-r11 > gcc-3.3.3, glibc-2.3.3.20040420-r0 and so on. > > It worked from time to time, but always gives me this error - > the kind request for sharing this error persuaded me to do so now. > Any ideas how I can get it to work more snappy are appreciated too :) You should be happy that it works at all! Given that it's running at USB 1.1's full-speed and not USB 2.0's high-speed, and given that it uses the somewhat obsolete CBI transport protocol (that's the "P 00" in your message above), you shouldn't be surprised that it's slow.
