Should work

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

Drops to 128 bytes per microframe, so up to 48 fit on one USB port at that setting.

Z-Star Microelectronics Bandwidth table read from a real `lsusb -v` dump. 7 isochronous settings, smallest 128 bytes per microframe. Seen on 6 machines in the dump corpus.

USB ID: 0ac8:c457
Fit on one USB port: 48 (at its lowest bandwidth setting)
Bandwidth floor: 128 bytes per microframe (from a real descriptor dump)
Every bandwidth setting it offers: 3072, 2688, 2048, 1536, 1024, 512, 128 bytes per microframe
Seen on: 6 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.
