The WebUSB specification defines a specific Platform Descriptor in the
Binary Object Store:
https://wicg.github.io/webusb/#webusb-platform-capability-descriptor
This descriptor provides a special 'Landing page' URL to the host
browser and associated privileges for it.
Bump the USB version for BOS descriptors to 2.1 to be compatible with
Chrome implementation.
