You have a HackRF One revision 9 which is the latest version. Because it has some different components, it has a new board ID, so your older version of 

Code: Select all

hackrf_info

 does not recognise it. If you update your libhackrf and host tools to the 2023.01.1 release, it will be correctly identified by 

Code: Select all

hackrf_info

.Aside from what is reported by 

Code: Select all

hackrf_info

 and flashing firmware with 

Code: Select all

hackrf_spiflash

, the difference should not affect your ability to use any software that supports the HackRF One.
