Thank you for uploading the logs. (Looking at them, it’s better to use
`util/cbmem/cbmem` instead of the Linux kernel module, as that does not support
the log level markers.)

Can you please elaborate, how you connect the keyboard then? Also with the
Radeon RX 6800XT, does the USB keyboard never work, or just when you connect it
to the USB Type-C port of the graphics card?
Is the port we are trying to use on the PCI address 03:00.2?

SeaBIOS detects a USB hub, but I guess it’s a different one?

How is your setup exactly? What keyboard is it, and how is it connected exactly?
Can you please try with SeaBIOS master, and also output `lspci -nn` and `lsusb`
and `lsusb --tree` from GNU/Linux?

Bug #414: X9SAE-V: No USB keyboard init with SeaBIOS while using Radeon RX
6800XT
https://ticket.coreboot.org/issues/414#change-1089
* Author: Aaron Burton
* Status: New
* Priority: Normal
* Category: board support
* Target version: none
* Start date: 2022-09-05
* Affected versions: 4.17
* Affected hardware: X9SAE-V
----------------------------------------
While booting coreboot 4.17 to SeaBIOS 1.16 on a Supermicro X9SAE-V, the
keyboard flashes on then off (LED Backlit USB keyboard) and does not let me
interact with SeaBIOS until the linux kernel is loaded on the OS side.
Currently using a PS/2 keyboard to unlock my boot drive via SeaBIOS. Using any
other GPU does not affect the USB keyboard and works just fine. The Radeon RX
6800XT is a reference card with a USB-C port on it, naturally I tried a USB-C
adaptor on the GPU to get the USB keyboard to work, but no luck. Building
coreboot with either native, secure VGABIOS loading, or libgfxinit does not fix
the problem either. Seems to be specific to this GPU on hardware init. Coreboot
dot config is attached.
