I am new to the hobby and am in the process of building my first rig. I've read several older posts about this topic, but figured I would start a new one to see if there are any current fixes. I"m running Astroberry on a Raspberry Pi4 via Macbook Pro. EXOS2 GT, ASI 533 MC & 120mm, and PA Focus Cube all connect well but the Pocket Power Box will not connect. It seems from what I have read on other threads that it may be a serial port mapping issue and not a driver issue. Should I work my way through the information on the Persistent serial port mapping page below?
