I've got an Asus ROG Strix X470-I (AMD/Ryzen) motherboard. Ethernet on it works fine, but I want to use the Wi-Fi and Bluetooth controller as well, but I can't figure out the right Kernel modules to load. In lshw I see these:

Code:

...
                 *-usb:2
                      description: Bluetooth wireless interface
                      product: Bluetooth Radio
                      vendor: Realtek
                      physical id: c
                      bus info: usb@1:c
                      version: 1.10
                      serial: 00e04c000001
                      capabilities: bluetooth usb-1.10
                      configuration: driver=btusb maxpower=500mA speed=12Mbit/s
...
                 *-network UNCLAIMED
                      description: Network controller
                      product: Realtek Semiconductor Co., Ltd.
                      vendor: Realtek Semiconductor Co., Ltd.
                      physical id: 0
                      bus info: pci@0000:05:00.0
                      version: 00
                      width: 64 bits
                      clock: 33MHz
                      capabilities: pm msi pciexpress cap_list
                      configuration: latency=0
                      resources: ioport:c000(size=256) memory:fe300000-fe30ffff
...


I've tried the rtl8821ae module, but that doesn't add a Wi-Fi device or give me any output in dmesg. If I run dmesg | grep -i blue, I see no Bluetooth messages either. I know I have all the right kernel selections for Bluetooth because I can plugin a broadcom dongle and it does show up in bluetoothctl and using the legacy hictool, neither of which detect the onboard bluetooth.

I'm a little confused that the onboard bluetooth seems to be listed as a USB device. Shouldn't it be connected to the PCI-E bus like the Wi-Fi adapter?

lsusb shows all the Realtek devices as having the id/vendor as 0bda:0411.

What kernel modules/options should I be selecting for this hardware?

SumDog,

Post the output of
Code:
lsusb
and
Code:
lspci -nn

We need the vendor and device IDs of both devices.

Google says that 0bda:0411 is a Device '4-Port USB 3.0 Hub'
That will need
Code:
CONFIG_USB_XHCI_HCD=y
CONFIG_USB_XHCI_PCI=y
in your kernel.
