GAN charger seems to reset USB-C negociation each instant

[RaitoBezarius]

I bought those of these shiny "GAN chargers" (Baseus, etc.), I tried multiple brands and it seems like this is constant across this type of charger: it cannot be used to charge a X2100.

I don't know if this is a:

• X2100's USB-C controller issue
• X2100's EC issue
• GAN charger USB-C controller issue

I plugged some USB tester in-between and it is losing power every second, I can see on the first bootup of the device there's some 20V and some current going through and then it dies.

I am willing to experiment / patch my EC / spend time on Ghidra to reverse this, but I wanted some input from the community if they ever experienced this. :)

Furthermore, I tried with an electronically marked cable and I see the same issue.
