Important notes on installation
1. Firmware version for DriverKit
Attention: Fireface UFX / UCX / UC / 802 and Babyface require a firmware update to versions UFX: 361, UCX: 49, UC: 127, 802 : 17 (111), Babyface: 226 , or higher, to enable the use of this DriverKit driver.
Link to firmware update tool:

While the firmware update tool would run on M1/2 machines, it needs a working driver. But the driver is not loaded if the firmware is not updated. So the interface firmware must be updated first, using a computer that runs the Kernel Extension driver, or a Windows computer.
