Can bus adapter not sending data

[Celestine]

That’s a bit hard to believe but I will certainly make some tests.
The Actisense, the ais (True Heading CTRX Carbon +) and a usb-serial converter is connected to a powered usb hub. This is fed by a 5v/3A supply. The pi has a Logitech wireless receiver, an O-charts dongle and a usb memory connected and is fed by a separate 5V/3A supply. The current consumption should be well under 3A in both cases. I never had an under voltage warning on the pi.
I will try without Actisense and also without ais and see if the other’s work ok then. The ais is possible to power directly from 12V. I will try that too. I can also try to swap the pi itself with my spare and see if that changes anything.
