2.4.8, USB storage, and FAT12

2.4.8, USB storage, and FAT12

[Damon Gunther]

Hi,

I just updated to 2.4.8 and I can no longer access the memory stick in my
Sony DSC-S75 camera via the USB camera connection.  This worked in
2.4.7 with the same config file.

The problem comes when I try and mount the SCSI emulated disk.  It gives me
the error:

jonx:~# mount -t vfat /dev/sda1 /camera
mount: /dev/sda1 is not a valid block device

If I do an fdisk to check the partition information:

jonx:~# fdisk /dev/sda

Command (m for help): p

Disk /dev/sda: 8 heads, 16 sectors, 991 cylinders
Units = cylinders of 128 * 512 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/sda1   *         1       990     63340+   1  FAT12

I noticed in the CHANGELOG that USB and FAT updates were made, so I don't
know which one of them is causing the problem.  I was using a modified entry
in unusual_devs.h to see the camera in 2.4.7.  This entry made it into 2.4.8.

I have vfat built as a module and I can mount my Windows partitions just fine.

Here is some dmesg output for more information:
