It kind of works. The serial console is silent. Serial over USB with "modules-load=dwc2,g_serial" does not work at all. WiFi misses firmware - so does not work. I think there are suttle differences between "0/1" and "W0" that are taken care of in raspbian but not in devuan. Most likely it's the firmware and the kernel. I had simillar problems with RPi3+, it also needs the latest firmware + kernel and des not work with the devuan rpi3 image.

Now this explains a lot - especially why the same procedure applied on RPi3+ worked.

All magic didn't work. Burned my stock of black candles, did other unspeakable thing, no use (The cat suvived! Would not touch the cat!). Migration from armhf to armel would work like a charm, if there was not the package manager that complains about not matching version numbers in armhf/armel and consequently not configuring the package. I have found no way to persuade that beast to ignore that pesky package suffix when the version number matches :-(

Now I try to transplant kernel+firmware from raspbian to devuan imag, let's see how that turnes out. I would be happy if I git a serial console working ...

Don't doubt that. But RPiW0 has USB-OTG direct from the cpu, RPi1 has a usb hub. That little difference turns out to be quite big. And the connectors don't match ... *sigh* ... but I need that USB-OTG, that's the reason for RPiW0 ..
