Hello All,
Here's the situation (Probably more info than you need but here goes)
I'm using an iOptron CEM120C with 3 USB 3.0 ports. A StellarMate (Rasp Pi 4) Connects to the following equipment:
ZWO ASI2600MC Pro Duo
Zwo Filter Wheel
Optec FocusLynx
Piggybacked on the main scope is a W/O Z73 with:
Starlight Xpress SX-46
SX Wheel (filters)

All of the above work just fine with no connection issues as long as I ONLY use the USB3.0 ports on the CEM120. Any attempt to use the USB2.0 ports cause connection problems.

Now I'm trying to add to the mix a QHY Q_Focuser. The only way I have to connect the focuser is through the bus on the SX-46. BUT, no matter how I connect the Q-Focuser (through the SX-46 hub, direct to the CEM120 USB 3.0, or even to the ASI2600 ports) I get the error message in the title. Logs are attached.
I've downloaded the latest versions of StellarMate, Kstars, and the drivers for the focuser. Don't know what else to try. Hope you can help.
Thanks so much for what you do.
Dean Misovich
