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

[bp]

I'm on a RHEL AS v3-update 2 box and my Sandisk 6-in-1 card reader just 
doesn't seem to play well.  The drive is recognized, appropriately labeled 
in the the messages & dmesg logs but I can't for the life of me mount any 
cards.  Card & drive are confirmed working on another box.  

dmesg lists it as sda.  How does Linux typically assign each slot on the 
reader?   sda1,sda2 or sdb1,sdc1 etc..?

Thanks.
