I understand that cloudmaker developed an INDI driver for USBFOCUS v3. I still have the earlier version v2. Does anyone know whether the older focuser would work under INDI?
There is now also an open source USB_Focus V3 driver included with INDI directly, you could try that and modify for V2 if the protocol is different. Simultaneously when the included driver was made I also happened to reverse engineer the protocol using a serial monitor on Windows and modified the Moonlite driver, it was quite simple as there isn't much the thing can do
