Analog stick desync with 4p dongle?

[FireCat1150]

Just recently got the 4p dongle and connected it to my nyko GameCube to USB adapter to connect to my PC. There seems to be some sort of issue where the stick will "stick" to a certain direction until it seemingly sorts itself out.

I've tried to fix it myself by doing some tests and it is consistent between controllers and versions. And even when I try to correct it, it keeps treating the stuck position as it center. Example: it is stuck to the right so I turn left and the end result reads my input as in the center.

My theory is that it has some sort of connection issue but I thought I'd try asking to see if there's a way to make sure the stick won't get "stuck".
