Can you test it? Do you have PD > with adjustable load? In fact I can't test it, I have a splitter and an adjustable load, not a splitter that can adjust it's own load. So I can't decrease the load of the splitter itself and reach this error condition. Regards, --=20 K=C3=B6ry Maincent, Bootlin Embedded Linux and kernel engineering https://bootlin.com
