The blk_base test case creates a USB mass storage block device with the Sandbox host block device as its parent. This does not make any sense and causes potential issue, for example if the test case tries to read/write anything on the USB mass storage block device it will definitely fail as its parent is not on USB bus at all. Correct the test case by creating another Sandbox host block device instead of the USB mass storage one and adjust the case accordingly.
