I can confirm that Your patch fixes the issue, enables the 2022.09.1
build and operations! I have managed to flash firmware
(hackrf_spiflash), read device info (hackrf_info), sweep some radio
frequencies (hackrf_sweep) and receive/transmit (hackrf_transfer).
Thank you HPS :-)

When it will be safe to provide port update 2022.09.1 to the port tree?

Should we create a separate comms/hackrf-2021.03.1 port for the older
systems where this LibUSB call is not available? Or maybe it will be
possible to build and update LibUSB on the older systems?

Port update to 2021.03.1 is ready:
