You should be fine. I also have a CGX-L, and only use the USB-B cable to the mount head when I need to run CPWI and PECTool. Otherwise, when running Kstars/Ekos, use the hand controller miniusb interface. From a cable management and robust PI4 perspective, I found the cleanest solution is to use a powered USB hub. Since the hand controller is only used for power-up initialization, I've velcro'd it to the front end of the dovetail plate and use the top end (RA axis) AUX interface. Only a power cord is required to come up on top from below. In my case, I added a bundled ethernet cable (fast transfers). The whole top end looks like the image....clean. I recommend the low end PowerBox and SSD replacement of the SD card too.  Good luck as you sort out your own config! CS Doug
