Hi Stefan, I am in contact with Cha at QHY. I am just wondering if the problem is the camera or the FW.
When I plug the QHY294M with FW in 4 pin mode into my indi server and immediately type in a terminal window:

dmesg

I get the following output:

[88253.519410] usb 1-10: new high-speed USB device number 5 using xhci_hcd

(ignore he long decimal numbers on the left).
This is exactly the same as I get without the FW.

Just wondering if it shows anything different when the FW is working and connected (4pin mode) ?
Thanks,
Nick
