"Well one thing is certain, if the OS doesn't see the device, INDI never will. So this appears to be either an OS-level, or hardware issue, and not an INDI issue."
"What does dmesg say when plugging in the device?"
Nothing, as for the OS, the EFW plugged to the hub simply does not exist .
You say this happens no matter what hub you use, and both on Raspberry Pi, as well as your laptop? Is that correct?
I tried to plug 2 USB keys to the camera hub : it Works, the keys are both available Read/Write.
Same if I plug the USB keys to a separate hub.
So it appears the EFW **IS** the problem.
I tried this set up:
- Focuser and ASI290mm plugged to the camera hub (USB port 1 on the Pi)
- EFW on USB port 2
- Mount on USB port 3
- Wireless joystick on USB port 4
Everything works fine, but I still don't understand why the EFW on a hub isn't detected by the system.
And by the way ... ASI290mm and EFW on a hub both work ... Under Windows ... Which excludes any EFW related problem
