Hello there. I have astroberry on rpi3 and it works well with my setup. Trying to upgrade to rpi4 8gb/64 class10 and there is a problem with connection to eqmod mount (I have az-eq6).
I disconnect all equipment including hub etc except mount, connect eqmod cable direct to rpi usb2 port. It connects and after ~30sec goes to reconnect.

I changed different power supplies for rpi4 5v 3a, nothing changed. When I connect to usb3 or another usb2 port ekos doesn't see mount at all. Only one port on rpi works but with cycle reconnect.

Astrberry image is up to date and upgraded/updated. Also added astroberry to dialout group.

Is the problem with rpi4 ports or eqmod cable (it is chinees noname but works great in windows10 and rpi3)?

I'm not fluence in linux, logs attached. Appreciate your advise.
