Ok, I just installed the CR4 XL into a Jasper 16mb console. The chip works fine and instaboots everytime. My question is that my USB ports are acting strange, If I unplug a controller and plug it back in, the xbox wont recognize it, even if it plugged in. Also the same with USB if I plug it in while the console is running it just freezes, but if I put it in before I turn on my console same with the controller everything works fine. Wondering if some experience people can point me to a solution. Not too worried if this cant be fixed its just an annoyance.
