After updating to the latest Windows 10 version my XBOX 360 wireless receiver was not recognized anymore and shown as “unknown device” in the device manager.
To fix this you´ll need to modify the “xusb21.inf” file that comes with the driver package as explained in this video:
You might have some trouble with enabling the testsigning for the now modified driver, especially if you are runnig Windows 10 Home. To fix this reboot your PC with this command "shutdown.exe /r /o /f /t 00".
Your pc will then boot into the advanced Windows options and there you can deactivate the driver signing for the next restart. Then you can install the unsigned driver, reboot the machine and enjoy your wireless controller working again.
