I've tried the patch and it failed.

the debug output is here:

These overcurrent warnings/errors also happen sometimes on windows when changing between battery and AC power or removing battery. Not very reproducible.

unlucky me :-(
I'll try to help on anything that's needed, on my free time, of course.
thanks for the help.
