After building a new file server this weekend I found that the internal flash media reader I addedd to it isn't working at all.

This is the dmesg output after scanning the device:

Vendor: Mitsumi Model: VT6205-DevB Rev: 2.67
Type: Direct-Access ANSI SCSI revision: 02
sd 0:0:0:0: Attached scsi removable disk sda

And this is what I get when I try to mount or read (cat, fdisk, etc) a SD card.

.....

And it goes on and on... It is clearly seen that the device is recognized and that it reads the basic information of the drive (ie. memory size, write protection) I read about this bug: http://bugme.osdl.org/show_bug.cgi?id=3223

But it is already closed, and for a very old kernel version, however it mentions something on adding this kind of device to unusual_devs.h... Is there something I must do?

Any other USB Mass Storage device and everything else works fine... Any recommendations would be very useful. :)
