Hi, I recently bought a raspberry pi 4B(4GB), yesterday I was excited to try my first attemp with it, but I had 2 issues I've encountered with:
1. Whenever I connected my USB(from the USB HUB) to the USB3 port, for a weird reason the wifi/hotspot stopped working, can't really tell why, it's a powered USB HUB, so it shouldn't draw too much power from the rasbperry pi.
Eventually I've simply connected the hub to a usb2 port and that fixed the issue.

2. After I solved the first issue, I ended up with another frustrating issue, I'm using a DIY focuser(ardufocus, which is compatible with moonlite focus drivers), for a weird reason, I didn't manage to get both my moun(EQMOD) and focuser to connect at the same time.
According to the connected USB's, both were connected, but I was only able to connect one at a time, if the EQMOD was connected, the focuser wasn't able to be found, and if the focuser was connected, I couldn't connect to the EQMOD.

I didn't manage to solve this issue, I also tried connected both of them directly to the raspberry pi and not through the USB hub, but that didn't help. Eventually after around 2-3 hours of trying to troubleshoot and google, I simply gave up, connected everything to the USB hub and then to my laptop and imaged with it.

Any ideas what could be the issue?
Thanks.
