DM USB: support multiple interfaces USB device 

This patch correct the USB request type which set wrong direction in
original code. It caused these important usb control transfer packets
send to phsical USB devices via libusb_control_transfer instead of
calling standard libusb APIs, likes libusb_set_configuration. From
libusb document, this is not the correct way:

"You should always use this function rather than formulating your own
SET_CONFIGURATION control request. This is because the underlying
operating system needs to know when such changes happen."
