Function Documentation

int _probe_descriptors	(	struct libusb_device *	dev,
		int *	cp,
		int *	ip,
		int *	ap
	)

Probe a USB device for a CCID interface.

Parameters:

	dev	ccidev_t representing a physical device.
	cp	Pointer to an integer to retrieve configuration number.
	ip	Pointer to an integer to retrieve interface number.
	ap	Pointer to an integer to retrieve alternate setting number.

Returns:

zero indicates failure.
