19:35 <digetx> tagr: hello, reminding about https://patchwork.ozlabs.org/project/linux-tegra/patch/20211130232347.950-34-digetx@gmail.com/

21:14 <digetx> jonasschwoebel[m: I'd expect that you should get EMI error message in a case of electrical problem, you should try to capture an compare all register changes that could be related to USB, like PMC and pinctrl, also could be that there is a "magic" EC command that does something
