Hmm, I'll have to look into this. My dongle is supposed to be backwards compatible.
what version do you have
it doesn't matter
the 4.0 was backwards compatible but for some reason it didn't work and I read how others dealt with the same issue
Maybe it was because I'm on win 8
I'll send the link of the adapter I use now
Btw are you using a ps3 or 4 controller?
