 macOS uses the plugged-in Bluetooth Controller. Please configure NVRAM as explained and try again after a reboot.
 
+### Broadcom/Cypress/Infineon Controllers
+During startup BTstack queries the Controlle for the Local Name, which is set to the Controller type (e.g. 'BCM20702A).
+The chipset support uses this information to look for a local PatchRAM file of that name and uploads it.
+
+### Realtek Controllers
+During startup, the libusb HCI transport implementations reports the USB Vendor/Product ID, which is then forwarded to the Realtek chipset support.
+The chipset support contains a mapping between USB Product ID and ( Patch, Configuration ) files. If found, these are
+uploaded.
