Hi, Whenever, software asserts, HC resets during xHCI initialization, host controller is setting PRC and CSC (one of the version of host controller sets WRC bit also). However, there is no handling of these bits in xHCI software. 1. At Initialization - device is NOT connected and due to HC RESET, is there any following bits should be SET HIGH or not? - PRC / WRC / CSC bit 2. At Initialization - device is CONNECTED and due to HC RESET, is there any following bits should be SET HIGH or not? - PRC / WRC / CSC bit I appreciate your valuable inputs. Thanks & Regards, Ankit A.
