Description of problem:
Just installed a fresh install of FC3-r1

I have an external USB dvd burner. It is correctly discovered by the
kernel and here is the messages from dmesg:

SCSI subsystem initialized
Initializing USB Mass Storage driver...
scsi0 : SCSI emulation for USB Mass Storage devices
  Vendor: _NEC      Model: DVD_RW ND-2500A   Rev: 1.07
  Type:   CD-ROM                             ANSI SCSI revision: 02
USB Mass Storage device found at 2
usbcore: registered new driver usb-storage
USB Mass Storage support registered.
sr0: scsi3-mmc drive: 40x/40x writer cd/rw xa/form2 cdda tray
Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0
usb 3-2: new full speed USB device using address 2

This is correct and an improvement over previous kernel version where
it was incorrectly found as a Revoltec device.


The problem is that when I run 'cdrecord -scanbus' I get weird
results, and not always the same response. For example:

This happens as both an user account and as root. Running 'cdrecord
-scanbus dev=ATA' correctly responds with my two IDE devices:

This may also effect k3b which also does not see the burner, only the
two IDE devices.

Version-Release number of selected component (if applicable):
