Mine behaves as multiple scsi devices, not multiple LUNs of a single  
SCSI device. In other words the four slots are sen as different  
devices, so:

/dev/sda is my SATA drive

/dev/sdb through /dev/sde are the four slots of the USB-connected  
card reader.

So if I plug in a USB flash drive it becomes /dev/sdf.

I do not have multiple LUNs enabled in my kernel. I do, of course,  
have USB mass storage enabled.

This is on a non-Myth Gentoo machine, I don't have a card reader on  
the Myth box, but I wouldn't think it would make any difference. An  
older Dell machine that I have running SuSE behaves the same way with  
a different USB card reader.

But of course, as always, YMMV.
