Don't buyOne bandwidth setting

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

Offers a single bandwidth setting at 1020 bytes per microframe, so only 6 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 1020 bytes per microframe. Seen on 12 machines in the dump corpus. Linux kernel uvcvideo uvc_ids[] quirk table entry, comment '/* Microsoft Lifecam VX-7000 */'. UVC_QUIRK_PROBE_MINMAX: device's Probe control rejects a GET_MAX/GET_MIN negotiation the spec requires; driver falls back to a simpler probe (device won't stream/negotiate formats correctly otherwise)

USB ID: 045e:0723
Fit on one USB port: 6 (at its lowest bandwidth setting)
Bandwidth floor: 1020 bytes per microframe (from a real descriptor dump)
Every bandwidth setting it offers: 1020 bytes per microframe
Seen on: 12 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.
