The USB receiver was not recognized when the software started. I suspected a hardware error.
I opened the USB receiver stick and examined the circuit. I discovered that a 16 MHz quartz component was defective. >> see picture
I replaced the component and the USB receiver was recognized again...
I've been playing fallout4 all day, I went into a elevator and it kept going, never stopped, waited 5 minutes, must of been a bug. How bout you, whatcha do today?
