You should be able to send vendor requests and standard requests to
an HID class device, such as a keyboard with libusb/usb_control_msg().
You don't have to claim the interface in order to send control
messages, at least to the device as a whole.

So: the vendor requests won't work if the device is, for example, and
HID keyboard, right? Because, if its an HID keyboard, the operating
system claims it and this precludes us from claiming it. Or am I wrong
about that?
