Fixes & Enhancements

- Fixed when a user initially connects a USB compound device (smart phone, etc.) to a USB 3.0 port, there is a possibility that will not be correctly detected (enumerated), unless it is first plugged into a USB 2.0 port on the same system. This driver update fixes this problem and allows device detection (enumeration) to occur correctly the first time a compound device is plugged into a USB3.0 port.
- Fixed when the Remote Wake Up executed by keyboard, the unwanted string entered. To solve this issue, you need to add the parameter(DWORD(32bit) value) to the following registry key. KEY_LOCAL_MACHINE\System\CurrentControlSet\Services\
usb3xhc\Parameters ForceHCResetOnResume 1h.
- Fixed when the hot plug operation is done with the external USB Hub, there is a possibility that the USB Hub is not detected. Note: This issue doesn't occur when the Selective Suspend Function is disabled.

- Not Applicable.
