i was having a simliar problem but the funny thing is that when i updated the driver, the hardware disappeared from the system all together...when i deleted the driver, the hardware now works perfectly, and is even recognized by windows device manager, but every time i boot up the first thing windows does is tell me my pioneer dvd rw needs a driver so i always click cancel and it says i might have some problems with it...but thats prolly not the best solution for you guys
