cdrecord'ing to a USB cd-writer?

[Robert P. J. Day]

  i just tried to plug in a USB cd-writer to an FC2-test1 box,
and based on the /var/log/messages, i'm not sure how to refer
to that new device.

  when i plugged it in, what showed up in /var/log/messages
was:
--------------------------------------------------------

----------------------------------------------------------

so i notice the usage of "udev" there.  running "cdrecord -scanbus"
shows me:

scsibus2:
        2,0,0   200) 'IOMEGA  ' 'CDRW9602EXT-B   ' '8OS4' Removable CD-ROM
        2,1,0   201) *
        2,2,0   202) *
        2,3,0   203) *
        2,4,0   204) *
        2,5,0   205) *
        2,6,0   206) *
        2,7,0   207) *

  i've tried various combinations of dev= referring to scsi addresses,
and even /udev/sr0, although i don't know near enough about udev to
know what i'm doing there.

  suggestions?
