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 280 machines in the dump corpus.

USB ID: 04f2:b681
Fit on one USB port: 3 (at its lowest bandwidth setting)
Bandwidth floor: 2048 bytes per microframe (from a real descriptor dump)
Every bandwidth setting it offers: 3060, 2751, 2544, 2304, 2048 bytes per microframe
Seen on: 280 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.
