>Description:
	Some CD-R drives report themselves to be type 4 (WORM), and are not
	attached as CD drives. (They can only be used as uk ('unknown').

>How-To-Repeat:
	Try to play a CD in a SONY CDU920S CD-R player.
>Fix:
	If the inquiry string for a removable WORM device begins CD-R, its
	probably safe to asssume it can be treated as a CD player. The
	following patch does that.
