Create a new usb control transport: This transport is for sending and receiving control information from the host to device using the Default Control Pipe.

Parameters

handle	a device handle that uniquely identifies a USB device
interface	the USB interface number for the control transport

◆ submit()

virtual ssize_t uhd::transport::usb_control::submit	(	boost::uint8_t	request_type,
		boost::uint8_t	request,
		boost::uint16_t	value,
		boost::uint16_t	index,

value	2-byte (wValue)
index	2-byte (wIndex)
buff	buffer to hold send or receive data
length	2-byte (wLength)
timeout	4-byte (timeout, default is infinite wait)

Returns: number of bytes submitted or error code
