This is all required for adding USB host MSC support in kernel.

Testing

The SCSI sub system creates /dev/sd* devices when a USB MSC device is connected. Use fdisk utility to create a partition and then use mkfs.<vfat/ext2> to format the device with vfat or ext2 file system if the media is not already formatted. Now device can be mounted using $ mount -t msdos /dev/sda1 /media/sda1 and then start using the storage media mounted at /media/sda1
