Don't buyOne bandwidth settingNot sold separately

Its own USB descriptors rule it out for a multi-camera rig.

Offers a single bandwidth setting at 3072 bytes per microframe, so only 2 fit on one USB port and the rest go dark. Not a camera to build a table on.

Bandwidth table read from a real `lsusb -v` dump. 1 isochronous setting, smallest 3072 bytes per microframe. Seen on 2 machines in the dump corpus.

What backs this
Its bandwidth table was read out of a real USB descriptor dump from somebody's machine. We have never held this camera, but we know exactly how much of a USB port it reserves.
