[TriLUG] USB 6-in-1 Readers under Linux

[Andrew Perrin]

You generally need to have the CONFIG_SCSI_MULTI_LUN=y set in your kernel
configuration, because the 6-in-1 is seen as multiple LUN's on a single
SCSI device. So each slot will be a different drive; on my machine it's
sdc, sdd, sde, sdf, sdg, sdh because I have two bona-fide SCSI drives as a
and b. You may get some information by using sg_scan to probe the LUN's,
or by doing an fdisk sda (b, c, d, etc.) to check the partitions.
