My other PC doesnt have USB ports, its a old k6-500 (ASUS ALI P5-A mobo). If i really wanted to check i could install my USB card on it for testing, but thats certainly last resort trouble shooting step.
but one thing i have done is replace the USB ports with a PCI card indsted of the on-board USB support that the KT7 has. That USB controller had serious issues with dropping devices offline, including my gamepad (not flight-stick)which doesnt have any issues now.
I also should note that i dont have a hub connected to the PC.
Last night i played for a few hours w/o a problems again so it seems the problem does not exsist any more. This has been bugging me for a month and now it just "goes away".. this flight stick is possessed!
im now just hoping the problem doesnt return.
It could have been something as futile as the USB device disconnecting from the USB card. Personaly i think those devices should mount more stable into the host device, they come unpplugged entirely to easy.
