Flash disk problem

[cbrands]

I have a problem with my buildin multicard reader.
when I insert a compact flash card it is not detected
I boot from a Knoppix 3.7 CD
lsmod gives me the following output

and the output from lsusb is


Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 002 Device 002: ID 0aec:3050 Neodio Technologies Corp. ND3050 8-in-1 Card Reader
Bus 001 Device 001: ID 0000:0000

So the card reader itself is detected
The command


ls /mnt

results in


auto cdrom cdrom1 floppy hd pts sda1 sda3 sda5 sda6 sdb sys test

My hard drive is sda. I think that sdb is the flash disk so Knoppix knows at least at some level that there it is there.
But when I try


mount -t msdos /dev/sdb /mnt/sdb

I get


mount: wrong fs type, bad option, bad superblock on /dev/sdb,
or too many mounted file systems

I dont know what to try next
Thanks

First, try fdisk -l to check what kind of partitions fdisk can see on your flash drive.

Depending on that you might want to try different filesystem types ( I am not sure if vfat is similar to msdos but I always use it to mount fat32 partitions).

[cbrands]

I tried vfat but that didn't help
I will try fdisk -l tonight when I get back home. At least I know that the hardware works as I did manage to get it working with
system rescue cd (http://www.sysresccd.org) :D
I am thinking that maybe some needed kernel module is not loaded.
Thanks for your reply nick666

What is the fstab entry for this device?
