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.

Bandwidth table read from a real `lsusb -v` dump. 7 isochronous settings, smallest 128 bytes per microframe. Seen on 31 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. UVC_QUIRK_FIX_BANDWIDTH: BANDWIDTH QUIRK: device misreports (usually over-reports) the isochronous bandwidth it needs in its probe/commit response; the driver recalculates/clamps it instead of trusting the device.

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.
