Hi, I own an internal Mitsumi 7 in 1 Floppy (floppy + 6 in 1 card reader)
Now the floppy works fine, but no matter what I do I can't get the card reader to read my SD card. I'm running kernel 2.6.15.4 with usb mass storage support enabled, I have the scsi disk support enabled as well, this is the output I get from cdrecord -scanbus

So it's there, the kernel knows the hardware is there it knows its a mass storage device as well, here is my messages output.

kernel: Vendor: USB2.0 Model: CardReader CF RW Rev: 0.0>
kernel: Type: Direct-Access ANSI SCSI revision: 00
kernel: sd 8:0:0:0: Attached scsi removable disk sdb
kernel: sd 8:0:0:0: Attached scsi generic sg1 type 0

But when I try to mount it with mount -tvfat /dev/sdb1 /mnt/sd (the directory exits)
it says no medium found (yet it checks the drive to see if there is anything in there)

Am i doing something wrong or is this device not supported by the usb mass storage driver?

Please review LQ tutorial hardware section for article on flashcard readers. Make sure your kernel config under SCSI support enables Probe all luns on each scsi device. Are you using udev and is it on? Good luck.
