malev: As BongoMan wrote on 2009-10-26, this also affects Karmic (9.10), which I can confirm, too.

It also affects one of my systems, an Asus UL30A-QX130V with BIOS v211 (running 9.10, linux-image-2.6.31-16-generic and linux-backports-modules):
Bus 002 Device 002: ID 058f:6366 Alcor Micro Corp.

While the SD device is correctly detected and a device node is assigned (/dev/sdb) attempts to mount with 'mount -v /dev/sdb /mnt/sdb' fail with:
mount: you didn't specify a filesystem type for /dev/sdb
       I will try all types mentioned in /etc/filesystems or /proc/filesystems
Trying fuseblk
mount: no medium found on /dev/sdb ...trying again
mount: /dev/sdb: unknown device

Specifying the filesystem as in 'mount -v -t vfat /dev/sdb /mnt/sdb' doesn't help:
mount: no medium found on /dev/sdb ...trying again
mount: no medium found on /dev/sdb ...trying again
mount: no medium found on /dev/sdb ...trying again
mount: no medium found on /dev/sdb ...trying again
mount: no medium found on /dev/sdb ...trying again
mount: no medium found on /dev/sdb

This linux-usb bug seems to be related:
http://bugzilla.kernel.org/show_bug.cgi?id=14228

Using 'sg_start -l /dev/sdb' as suggested there does not help, it just prints:
open /dev/sdb with flags=0x802
    Start stop unit command: 1b 00 00 00 03 00
