Problem description:

- I get the following "USB device not recognized" notification when connecting Xbox One controller:

The last usb device you connected to this computer malfunctioned

Troubleshooting steps taken:

- Restart computer multiple times

- Try with 2 additional USB cables

- Try all 3 cables in different USB slots

- Uninstall controller in Device Manager, then reconnected controller. Devices is re-added with same error message:

"Unknown USB Device (Device Descriptor Request Failed)"

Observations:

- When I tried plugging controller into the keyboard's built in USB sockets, it caused the keyboard and mouse to suddenly stop working and appear to power down until restart.

- This controller has never had this problem on this device in the past, and has previous worked perfectly with all 3 cables I used in testing.

Any additional troubleshooting steps you can suggest? Thanks in advance.
