kernel 2.6.8.  ioctl ("/dev/hdc", CDROM_SEND_PACKET, cmd)

commands that are failing as non-root, even when permission is granted
rwxrwxrwx to /dev/hdc, are, according to some debug info added to k3b:

	GET CONFIGURATION (46)
	error code: 0
	sense key: NO SENSE (2)
	asc: 0
	ascq: 0

and:

	MODE SELECT (55)
	error code: 0
	sense key: NO SENSE (2)
	asc: 0
	ascq: 0

the result is that k3b cannot determine that the drive exists, therefore
it cannot use it even though cdrecord might actually work.


as root, the following errors occur:

	MODE SELECT (46)
	errorcode: 70
	sense key: ILLEGAL REQUEST (5)
	asc: 26
	ascq: 0

	READ DVD STRUCTURE (ad)
	errorcode: 70
	sense key: NOT READY (2)
	asc: 3a
	ascq: 0

presumably it can be concluded that the GET CONFIGURATION ioctl command
is the one at fault.

... what gives?
