Re: USB Card Reader.

Thanks to all who answered.  Much appreciated!

The driver is usb-storage and is loaded automatically as your syslog says.
It creates devices /dev/sda , sdb, sdc and sdd for the different types of cards.
So you should try (as root)
mount -t vfat /dev/sda /media/card
and the same with sdb, sdc, sdd (or maybe sda1 etc.) until you have found the
right one for your type of card.

Later, you can create an appropriate entry in /etc/fstab .


Progress!  well, some.

I did "mkdir /media/card" so that there'd be a directory there to attach to.

I tried each of the possibilities:

mount -t vfat /dev/sd[a-d] /media/card

Mount told me that a, b and d had no media but c gave me an error message:

Yewdales-lodge:~# mount -t vfat /dev/sdc /media/card
mount: wrong fs type, bad option, bad superblock on /dev/sdc,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

I looked at dmesg | tail:

scsi2: ERROR on channel 0, id 0, lun 2, CDB: Read (10) 00 00 00 00 06 00 00 02 00

FAT: bogus number of reserved sectors
VFS: Can't find a valid FAT filesystem on dev sdc.
FAT: bogus number of reserved sectors
VFS: Can't find a valid FAT filesystem on dev sdc.

I also tried Duncan's suggestion of mounting /dev/sdc1.

Yewdales-lodge:~# mount -t vfat /dev/sdc1 /media/card
mount: special device /dev/sdc1 does not exist

Two things come to mind. Either the card uses some other fs type or I've lost all the pictures on it.... :( Of course, I'm not sure what the dmsg error message means precisely, but "unable to read partition table" sounds bad. That doesn't depend on the fs, does it?
