236 The bmControls attribute and the baSourceID attribute are multi-value attributes.
239 need to write two values to bmControls, like so:
243 cat << EOF > bmControls
251 The bControlSize attribute reflects the size of the bmControls attribute, and
253 attributes are automatically increased / decreased as you set bmControls and
260 $ cat bmControls
268 $ cat bmControls
272 $ cat bmControls
281 The Camera Terminal and Processing Units in the UVC chain also have bmControls
