@Morgan:
Realy? At least 4 members in my SQ had a problem like yours or like soldano’s and with this HUB now they are all ΟΚ.
Ι cant think something else.
Changing the cougar for a new one solved most of my electronics issues
The last problem I had was related to bad usb plug
And then I have the undelaying problem of the FCC2 which is too dépendant on temperature
Of course my airbrake switch broke , like most people but with proper resin I was able to repair it
And the monster play I had on the stick was solve with proper cork at the right places 🙂
As I said voodoo + luck + heavy maintenance has always been needed with this POS
