static sptr uhd::transport::usb_control::make	(	usb_device_handle::sptr	handle,
		const size_t	interface
	)		[static]

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

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,
		unsigned char *	buff,
		boost::uint16_t	length,
		boost::int32_t	timeout = 0
	)		[pure virtual]

Submit a USB device request: Blocks until the request returns

For format and corresponding USB request fields see USB Specification Revision 2.0 - 9.3 USB Device Requests

Usage is device specific

Parameters:

request_type	1-byte bitmask (bmRequestType)
request	1-byte (bRequest)
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:
