Mounting USB card reader

[coyote]

I'm having difficulty getting my USB card reader to be recognised.

I get the error:

mount: /dev/sda1 is not a valid block device

Any ideas?

I've had that error before with my usb key, i just took it out and tried again.

I've tried many things, including that.

'dmesg' should show the info you need when you plug in the card reader. it sumtimes changed to /dev/sdb and so on.

Cosult this bugzilla entry for posiible solution:

You may also want to try turning off the USB device, rebooting, turning it back on and then trying to mount it. Also check that the usb-storage module is loaded by issuing
`/sbin/lsmod | grep usb-storage`

shouldn't that be "grep usb_storage"?

is this a usb flash key device? and if so here

Some drives may not "show up" as the #1 device. For example, my USB Zip drive (yes, I actually have one - for backups only, these days) is /dev/sb4. Try this:

dmesg | grep sdx

Where "x" is a, b, c, ... until you find it. It's a bit of a pain sometimes, but look at it as a learning experience...

I have Usb card reader (4 in 1), too. and I faced the same problem that you face. but when I

googled the net I found this page:

and thanks god.. the cards reader work correctly (on FC3).

try the following:
add 'options scsi_mod max_luns=8' to /etc/modprobe.conf.
the "max_luns" must be equal or greater than number of your card's slots.
plug in the card reader (don't forget to plug the card in it's slot too) then reboot your

system...

run "hwbrowser" and if you find new drive under Hard Disks go and mount your desk:
Example:
mkdir /media/CompactFlash
mount -t vfat /dev/sda1 /media/CompactFlash

I hear someone say that you should update the kernel. Although I didn't updated the kernel,

the card reader worked correctly.

good luck...
