Doing "fdisk -l /dev/sda" gives no result (it just returns).
The device is being recognized as a ND5010 Card Reader from Neodio Technologies Corp. using lsusb and lsusb -s 003:002 -v. Furthermore the disk is recognized correctly by cat /proc/bus/usb/devices as a USB Storage Device.
Anyone know what's wrong?
You may have a problem like I did this weekend:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=110653
The Fedora/Red Hat kernels don't have multi-LUN support (basically one device with multiple disks). You can manually add the LUNs in /proc:
echo "scsi-add-single-device 0 0 0 1" > /proc/scsi/scsi echo "scsi-add-single-device 0 0 0 2" > /proc/scsi/scsi echo "scsi-add-single-device 0 0 0 3" > /proc/scsi/scsi
See if that helps.

</gratitude-mode> Fantastic! Great! This is it! Thank you very much!! <gratitude-mode>
And thank you for documenting the bug. It works like a charm. I'm very content I can finally read the bugger.....
What I wonder about is, how did you find the error and how did you find the statements to correct it?
It took me an hour or two of googling to make some sense out of it. Originally I was trying to mount /dev/sda1, because I thought that it would only see one slot at a time. I eventually found Question 9 under Trouble Shooting from the FAQ on http://www.linux-usb.org/. From there it was just testing and documentation.
I created a patch for USB hotplug that should look at your scsi devices and send the lines automatically. If you get a chance, try it out (and remove the scsi-add-single-device lines you may have added elsewhere.
To use this patch, su to root and cd to /etc/hotplug. Make a backup copy of hotplug.functions (cp hotplug.functions hotplug.functions.orig), and run patch: patch -p2 < /path/to/hotplug-multilun.patch
Unplug the USB card reader, and plug it back in, and then look at /proc/scsi/scsi to see if you have more than one device for you card reader. I have only tested it a few times, but it works for me. Let me know how it works for you. If it works for you, I'll post it on bugzilla.
