This SWI registers a new host controller with USBDriver.
If USBDriver knows that the API version in R1 incompatible with its current expectations, then the registration will be rejected.
The R1 parameter was introduced in USBDriver 0.49; for safety it’s recommended that host controller modules check USBDriver_Version and refuse to register if USBDriver is too old to support API version checking.
