Hi, I have a USB keyboard that works in UEFI apps (and grub) but if plugged into a dock stops working when Linux boots. It works when hotplugged into the dock or plugged into the laptop directly before or after booting. A mouse plugged into the dock does not share this problem. (I have no other keyboard to test at hand.) Kernel version: 5.1.18-300.fc30.x86_64 XHCI USB controller: Advanced Micro Devices, Inc. [AMD] Raven USB 3.1 Hub: 17ef:a38f Lenovo USB2.0 Hub Keyboard: 04d9:0192 Holtek Semiconductor, Inc. USB-HID Keyboard Relevant kernel messages are attached. My ignorant initial thought is that the hub should be transparent to the keyboard, so that the fault is unlikely to lie with the keyboard. I have unsuccessfully tried the delayed initialisation quirk on the keyboard. I have asked the Fedora kernel developers about this problem first -- they told me to ask here. Thanks for your help.
