I use R7-5800 + B550M + RX5500 + BCM943602CS (with M.2 adapter). I've successfully installed Big Sur and done usb mapping in it (although all USB ports work without mapping). The two things not working in Big Sur are (i) the Bluetooth which is pre-integrated in the motherboard (but I don't need it in desktop PC); and (ii) the HDMI port of RX5500 not transferring audio (bought a DP-to-HDMI line to bypass the issue). Since I've got another RX6600XT, I tried to upgrade Big Sur to Monterey 12.4. Without change in EFI, the setup stuck at detecting the mouse. I use logitech mouse and keyboard with a unifying adapter plugged in USB2.0 and it works well in Big Sur. The things I've tried but not working: - USBInjectAll / XHCI-unsupported : not working in AMD as expected - SSDT-RHUB - XLNCUSBFix / AMD StopSign-fixv5 Any suggestions will be appreciated.
