Trying to get Lexar card reader working on laptop


Hi,
I'm trying to get my Lexar usb card reader (model #gs-ufd-20sa-tp) to work on my laptop (Asus M50VM) running Ubuntu 10.04 LTS.

When I connect the reader (with a pcmcia flash card in it), dmesg says this:
[115625.181613] usb 7-2: new full speed USB device using uhci_hcd and address 4
[115625.334337] usb 7-2: configuration #1 chosen from 1 choice

but it doesn't seem to do anything else. It's an older device, and I've tested it on an older laptop running XP and it works.

thanks,
Christopher.

I have an Optex usb card reader. It automounts on Ubuntu 10.04 LTS. When I run 'lsusb' command it shows up like this:

Quote:
Bus 002 Device 003: ID 55aa:b000 OnSpec Electronic, Inc. USB to CompactFlash Card Reader
Run lsusb in a konsole and post the results. Your ID will be different, since that is set up by the manufacturer.

Look in your /media directory. On LTS there is another directory; /media/disk/ and in there are the files on the memory card. I put a card in from my camera.

If the card is not mounted ( it may not be if automount is disabled ) you can always run a mount command as root, and mount it in a empty directory. Then your files should be there.

The card reader is there.

What do you see in /media ? I assume you have a memory card in the reader.

It's not automounted (only thing under /media is cdrom and cdrom0 and cdrom is linked to cdrom0).

What device do I use to mount? (ie mount /dev/???? /mnt/whatever)

thanks,
Christopher.

That depends on what other disks you have. Open a konsole, go into the /dev directory, do an 'ls -l sd*' without the quotes, and see what it lists. Your HD will probably be sda and you should see a sda1 for the first partition, and one for each other partition. If you have one HD, then look for a sdb and sdb1.

On my system I have two HD's so the memory card becomes sdc.

It's like it's not recognizing the card in the device. Removing or reinserting the card doesn't seem to get any reaction from dmesg.

Hmmm, not sure what to suggest.

Here is what I see in dmesg when I plug in my usb memory card reader.
