HereLink V1.1 controller won't go into Fast Boot mode

I tried to do the latest HereLink controller update today.

Following the CubePilot wiki instructions, I plugged my controller into my PC and simultaneously pressed the power and “D” button. The only thing that happened is that I periodically got the tones on my PC indicating a USB device being connected and disconnected.

I haven’t tried the over the air method yet. I think I’d like to make sure the pc/usb method works.

Thank you!
