Hello, I am dealing with the same error…

Win/10/64…

I have tried the direct update but the update is not possible.

Also the device, when is recognize , is recognized as "Unknown" ..

Are you using the latest version of H9 Control? The latest Direct Updater is also bundled with the latest H9 Control. Did you power up your H9 with HOTKNOB button pressed and hold to boot into UPDATE mode before using the Direct Updater?
