USB Problems - SanDisk ImageMate

[nipper]

I'm having some problems mounting my USB SanDisk ImageMate flash card reader. I've done Googls searches and read the Linux USB sub-system document but still can't seem to get it going.

When I try and mount the device, I get the following:

# modprobe usb-storage
# mount -t vfat /dev/sda1 /mnt/flash
mount: /dev/sda1 is not a valid block device

Based on my searches, this seems to be a common problem, but I can't seem to find a good answer. I've tried sda4, etc., but still the same thing.

The output of # cat /proc/scsi/scsi is:

Is there anything obvious I'm missing? Can anyone offer any insight? Sorry for the long post...

I checked the /var/log/messages and found this piece in it:

Any ideas anyone?

Well, I'm trying to work this out on my own, but I keep hitting snags...

If I mount using usbdevfs, rather than vfat, it mounts -something-, but not the cardreader where I can read the Memory Stick.

It just gives a few directories of nothing or what looks like device files.

Anyone? Please?

You do have a flash card in the reader when trying to mount?

[nipper]

I have the Memory Stick card in, but not a CompactFlash card (don't have one). It's a dual reader for both CompactFlash and MemoryStick.

Do I have to indicate which medium to read?
