Hi,
It is likely that your system handles USB PD in firmware, and the OS
has no say in that. Which board is it?
It's a "Gigabyte Z170X Ultra Gaming", which I (obviously) don't use for
gaming ;)
You should be able to see the USB Type-C ports under
"/sys/class/typec" if your board supplies some kind of an interface
for the OS to them.
% ls /sys/class/typec
Unfortunately, the directory typec doesn't exist in /sys/class.
To check if your system supports UCSI:
% cat /sys/bus/acpi/devices/USBC000\:00/status
15
The device doesn't exist, either.
If you don't have the device (/sys/bus/acpi/devices/USBC000\:00), or
if the status reads 0 instead of 15, UCSI is not supported in your
system.
What does that mean, UCSI is not supported? Is that something that might
be fixed somehow, or do I have to live with that?
Thanks a lot,
L. Rose
