Psy1280 Are you suggesting an external USB hub that I would connect to the ASIAIR? If so could you tell me how the hub would connect to the ASIAIR?
Yes, when you don't have enough ports on your desktop computer, you add a USB hub. Same thing with the ASIAIR.
I have a series of hubs in my setup, in fact.
Since ZWO does not publish the power ability of their USB ports, I connect a single port of the ASIAIR to a powered USB hub. And leave all other ports of the ASIAIR unconnected.
This powered hub serves as a USB port with a known power capability.
This powered hub (inside a weatherproof box at the base of my Mortar tri-pier that sits outdoos 24x7 (except currently indoors to be swap a third generation ASIAIR with a fourth generation ASIAIR). A Samsung T5 SSD is also plugged into this hub.
One port of this powered hub then feeds another (unpowered) USB hub that sits on my duall saddle plate up on the mount.
That saddle plate hub then feeds subsystems (main OTA, sub OTA and mount, etc).
The main OTA has its own (unpowered) hub to feed the camera, filter wheel and electronic focuser.
The sub OTA has its own (unpowered) hub to feed the guide camera and the electronic focuser for the guide scope.
Just get a hub from some reputable manufacturers at Amazon. I use a Startech as my powered hub since I use a USB-C cable to go from my weather proof box to my saddle plate. But I have also used Anker and ACASIS powered hubs successfully.
For the unpowered hubs at Amazon, I have used StarTech, UGreen, ICSI, Atolla, Uni, etc successfully with the ASIAIR.
