No, the point was to run lsusb as root at 10G speed. As root, it will request
the BOS descriptor (bypassing the patched kernel code) so we could see if the
device has a temporary problem with BOS at that particular stage of
enumeration, or if it's completely broken and never responds to this request.

I think it may be completely broken, because I installed Wireshark on Windows
and it looks like my Windows 10 doesn't fetch BOS descriptors from SuperSpeed
devices at all (maybe it does from hubs, I haven't tried).
