Re: focus motor not recognized anymore.
It is easy to find out that USB allows for 127 devices. Easy and misleading. 127 is a theoretical upper limit. In practice, it will crap out long before you get near that number. So check how many USB devices you have connected. If you have a lot, disconnect anything non-essential. I found that removing a security camera and my sky camera improved the USB reliability considerably.
Check how many hubs you have between the device and the computer, and minimize the number. An active extension cable is a hub. A seven-port hub is two 4-port hubs connected in series. Four of its output ports are one hub farther from the computer than the other three. There are probably several hubs inside the computer.

Re: focus motor not recognized anymore.
Little clarification: USB protocol can handle 127 devices (HUBs are devices too), and all devices need to be known to the USB host (master, the devices are slaves), and usually the host can't handle nearly that many devices. The OTG USB is capable of changing roles (device can become host and vice versa), but the device count stays. The only solution is connecting some devices to another USB host, that can talk to the computer via, say, ethernet.KathyNS wrote: ↑Tue May 24, 2022 12:33 pm I have been hassling with connectivity issues for a while. I assume the focus motor is connected via USB, so some of my experience might be applicable.

Re: focus motor not recognized anymore.
Also even plugging it to your computer and checking with the device manager, you could see if the computer found an unknown new USB device. The USB VID is probably 19B4.
[edit]
"The USB VID is probably 19B4."
Or then not. It looks like Celestron hasn't use their VID much. It's probably something else.
Maybe you could ask the VID (Vendor ID) and PID (Product ID) numbers from Celestron?
The computer uses those numbers to match the USB HW and the appropriate driver.
If you have something else Celestron that you can connect to your PC via USB,
there is a good chance that those parts have the same VID.
At least you can check if an unknown USB device emerges in the device manager, when you plug the focus motor, and disappears when you unplug it.
If you have Linux, you can use "lsusb" console command. (I guess it works for Macs too.)

Actually those adapter chips can be used for many different USB-adapters - even USB-JTAG, but they are mostly used as USB-serial (RS232, 5V or 3.3V) adapters.
