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

Drops to 1936 bytes per microframe, so up to 3 fit on one USB port at that setting.

Bandwidth table read from a real `lsusb -v` dump. 4 isochronous settings, smallest 1936 bytes per microframe. Seen on 23 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.

USB ID: 17ef:4811
Fit on one USB port: 3 (at its lowest bandwidth setting)
Bandwidth floor: 1936 bytes per microframe (from a real descriptor dump)
Every bandwidth setting it offers: 3072, 3060, 3012, 1936 bytes per microframe
Seen on: 23 real 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.
