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

[Aaron S. Joyner]

Disclaimer: I am making assumptions based on my experiences with card 
readers in general, not your particular device.

Generally, devices like this are simple USB Mass Storage Controller 
devices.  One "controller" for each slot.  So effectively, you end up 
with a "device" for each card type, so that say Compact Flash cards will 
be /dev/sda, Sony MemoryStick will be /dev/sdb, etc.  How you access 
those devices will depend on how the media is formatted, but generally, 
using CF as an example:
/dev/sda is the device
/dev/sda1 is the first partition on that device, very likely FAT16 formatted
You can mount the device with `mount /dev/sda1 /mnt/foo -t vfat`

Generally, if you've found the device in dmesg, and seen it identified, 
the hard part is over.  Give the above a shot, and if you're still 
having trouble, let us know here on the list.
