– Does it behave the same when no other USB device is connected?
Yes. I have tried it with everything removed.
– Does the installation of the ControlBlock driver run through with any errors?
– Which OS are you using so that I could test it out on my site?
Raspian Jesse 4.1
– Which driver are you using? The ones for ControlBlock rev. 1.x or 2.x?
I have tried both. Currently 2.x (clean reimage in between).
– Are you using a toggle or a momentary switch? The ControlBlock needs a toggle switch.
I am using a push toggle switch – not a momentary.
