Hi everyone, I have been a long time user of that ZWO 290 and 120 before.
It actually works perfectly with a USB-A to USB-C (camera side), but it is not recognized at all with a USB-C -> USB-C cable. Usually it's a configuration we test less since our ASLAIR & mini pc have more USB-A... but it turns out I wanted to try the Mele Quieter 3c with USB-C.. And it's impossible to make it work.
I tried other usb-c devices (camera, hard drive, ssd) and they do work, so it's definitely coming from the ZWO 290mm mini (and 120). It would be great to have some feedback on that from ZWO; do they need a special usb-c usb-c cables (it looks like it)
