This patch fixes the usage check in the device detection: - Instead of usage 0x21, we now check for usage 0x01 as mandated by the FIDO2 spec, § 11.2.8.1 [0]. - Instead of using the last usage value in the USB descriptor, which belongs to an endpoint and not to the device, we now use the first (non-zero) value. The descriptor parsing could still be improved, but this should fix compatibility with all compliant FIDO2 devices.
