Keyboard works when routed through a USB 2.0 hub. Problem also exists under v4.20 kernel (12/23/2018 20:30 build, commit level 8fe28cb58bcb235034b64cbbb7550a8a43fd88be). Other USB 1.1 (mouse) and 2.0 (DVD writer) devices work when plugged into 3.1 ports. Latest level of Intel Visual BIOS (BECFL357.86A.0056.2018.1128.1717) properly handles keyboard edits of BIOS.
