Only 3 fit on one USB port, so it cannot cover a table.

Drops to 2048 bytes per microframe, so up to 3 fit on one USB port at that setting.

Bandwidth table read from a real `lsusb -v` dump. 5 isochronous settings, smallest 2048 bytes per microframe. Seen on 159 machines in the dump corpus. 2 different tables were reported for this ID, which usually means it enumerates differently on USB 2 and USB 3 hosts.

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.
