In function libusc_get_servo_status(),
unsigned int bytesRead = libusc_control_transfer(dev, 0xC0, (unsigned char)REQUEST_GET_SERVO_SETTINGS, 0, 0, (unsigned char*)buffer, size);
returns value 0xFFFFFFF7, which corresponds to -9, or LIBUSB_ERROR_PIPE
The error is not returned to the calling function - return value is always 1.
libusc_get_num_channels() and libusc_set_target() are working correctly, so valid Maestro controller is connected.
