Should work

Its measured bandwidth table says a table's worth fit on one USB port, but nobody here has run it.

Drops to 256 bytes per microframe, so up to 24 fit on one USB port at that setting.

Bandwidth table read from a real `lsusb -v` dump. 2 isochronous settings, smallest 256 bytes per microframe. Seen on 97 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.
