add this:

<*> Low Performance USB Block driver because it's not sda device, it's uba.

180 block	USB 块设备(U盘之类)
		  0 = /dev/uba		第1个USB 块设备
		  8 = /dev/ubb		第2个USB 块设备
		 16 = /dev/ubc		第3个USB 块设备

it's ok to choose <*> Low Performance USB Block driver

but mount /dev/uba1 /mnt/

del this:

<*> Low Performance USB Block driver

I think it's best to del this option. "mount /dev/sda1 /mnt/"
