cd-rw glitch: USB 2.0, nautilus-cd-burner

[David L Norris]

Nautilus CD Burner doesn't see my (I think: LITE-ON 52x/24x/52x) CD-RW
now that it's in an external IDE to USB 2.0 drive box.  The drive works
wonderfully with cdrecord, though.  The drive is detected and works with
nautilus-cd-burner when connected directly to the PCI IDE bus.

However, the problem is not nautilus-cd-burner.  I traced from the glade
dialog back through the code and found it has a function linux_scan()
which asks Linux for drive capabilities using what appears to be a
proper method (read /proc/sys/dev/cdrom/info).  Linux simply reports the
wrong capabilities through the cdrom proc interface.


I probably should report this as a bug somewhere, yes?  Where?  Clearly
a kernel bug and it may well be fixed in 2.5.  Should I at least try a
2.6 test kernel?

In the mean time I'll just hack my local nautilus-cd-burner to use an
alternate info file.  I just can't live without that.  (All else truly
stinks. ;-)
