v.v. = vice versa 
The problem with the bug over here is, that sometimes it decides to stay away just like that. A simple power cycle doesn't help to get it back, and I have to pull the battery to get the bug back. It also helps to remove the 28mm macro and mount the 18-55m to get it back. I also tried if manipulating the SD card with my W10 laptop helped, it seemed at first the bug would return by simply copying and removing some files to the card but i'm having a hard time reproducing that. I'll try a more scientific approach.
The pinning for the EF/EF-M adapter checks out, but i'm measuring pin 1 & 2 of the EF-M are connected to the metal bajonets, so that must be GND and not VBAT. Also, i'm getting around 680 ohms between pins 7 and 9 (CLK) so it looks like Canon inserted a resistor somewhere.
