The Xbox Wireless Adapter is currently unusable due to a driver conflict and missing firmware.
Required Fixes:
Blacklist: A conf file is needed with blacklist mt76x2u in /usr/lib/modprobe.d/.
Firmware: The firmware installer is required to grab the proprietary firmware using the upstream script, as the binaries cannot be bundled: https://raw.githubusercontent.com/dlundqvist/xone/master/install/firmware.sh
