Don't buyOne bandwidth setting

Its own USB descriptors rule it out for a multi-camera rig.

Offers a single bandwidth setting at 3072 bytes per microframe, so only 2 fit on one USB port and the rest go dark. Not a camera to build a table on.

Bandwidth table read from a real `lsusb -v` dump. 1 isochronous setting, smallest 3072 bytes per microframe. Seen on 205 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: 1224:2a25
Fit on one USB port: 2 (at its lowest bandwidth setting)
Bandwidth floor: 3072 bytes per microframe (from a real descriptor dump)
Every bandwidth setting it offers: 3072 bytes per microframe
Seen on: 205 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.
