Card reader not recognized?

Hi I have an internal sd card reader attached to the usb bus and I can't access it. Anything I need to do? When I put in a sd card with photos on it the green light comes on and I can check my /var/log/messages.log and I can see that it's sdf that's being accessed.

I've made a folder in /media named usb

/media/usb

and my fstab I've added  the card reader

/dev/mapper/isw_beggihedjf_ARRAY3 / ext4 defaults,noatime 0 1
/dev/mapper/isw_beggihedjf_ARRAY4 /home ext4 defaults,noatime 0 1

but when I try and mount I get

$ mount /media/usb
mount: /dev/sdf: can't read superblock

Any ideas?

Re: Card reader not recognized?

dmesg says "unable to read partition table", so the card is being detected, but it's not being read correctly. Same thing happens with mine - I use an external card reader instead, so fixing it is not on my to-do list.

Re: Card reader not recognized?

The card reader's documentation says that kernels 2.4 + will automatically recognize the reader, so I'm not sure what to do. Any recommendations for a card reader that's been proven to be compatible?
