I don't know your specific unit, but all the ones I have run into
use the usb_storage module. It will appear as 1 or more SCSI drives
to the system. Most cards will auto-mount off of on a mount point
off of /media.
You may want to take a look /var/log/message when you plug the
reader in if you are using it externally.
THanks. That helped a little. I modprobed the usb-storage module and it
recognized the various readers as sdd through sdg. Tor those who don't
know about it, /dev/disk/by-id shows the id's of all disks and
partitions. In this case, the CF, SD, SM and MS reader instances were
listed by number, but the SD was xxxx:0 and therefore sdd.
When I tried mounting it however the best I could get was Unable to read
partition table, and VFS cant find a valid FAT filesystem on sdd.
Changing the filesystem did not help either.
It may be the card, but I do not know...
There has been some discussion on the linux-kernel list about some readers/cards
(right around 2GB) having non-512 byte block sizes and their being issues with
that, it may be a combination of card and reader not doing things quite right.
What does is say when you plug it in?
