I was trying to do some programming on my H9 and kept getting interrupted by "communication error with device". I tried another cable, same thing. Tried different ports, same thing. Turned it off and on and now impossible to connect. Bluetooth connection works fine. Never had this problem before. This is on Windows 10 desktop. The pedal is up to date.Is it broken?
Could you please try "Reset settings" -> "Reset all settings" in the Settings page in H9 Control?
