Problem again sorry!

So I’m thinking this could be a user problem now but if you’ve seen my past thread I’ve stated that it wouldn’t work and it’d just loop or blink once and turn off however, would you think it’s possibly my controller that could be faulty? I’ve had one outcome twice with my first keymander2 and this new one I was sent (thanks to the very very helpful employees at iogear and very kind which I greatly appreciate) and the out come is, it won’t work at all unless if it’s put in the mouse and keyboard and not emulator mode or it’ll work in emulator mode for just like maybe 3 seconds tops and then dummy controller will die out on me, [note I am using a 3.1Amp adapter to for the extra power and I’ve used two different rooms and both rooms had the same outcome]
