Default = ‘1’ BIT17 : Connect Status Change (CSC) It is clear that the XHCI controller has received a disconnect event from the UPS. Can you check the other OS'es where this supposedly does not happen, if the UPS device attaches to the XHCI or EHCI controller? Did you start any driver for the UPS? --HPS
