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

◆ submit()

virtual int uhd::transport::usb_control::submit	(	uint8_t	request_type,
		uint8_t	request,
		uint16_t	value,
		uint16_t	index,
		unsigned char *	buff,
		uint16_t	length,
		uint32_t	timeout = `0`
	)

pure virtual

Submit a USB device request: Blocks until the request returns

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: number of bytes submitted or error code
