DirectInput8 EnumDevices sometimes painfully slow

Question

Sometimes (in about 50% of runs), EnumDevices takes 5-10 seconds to return. Normally it is almost instant. I couldn\'t find any other reports of this kind of behaviour.

Answer 1

Got same issue when having my Corsair K55 Keyboard. Changing the keyboard of USB port fixes the issue for a while, but then it comes back later on. So it seems to be a buggy drivers issue.
