I recently set up a MINISFORUM UM750L Slim with a Ryzen 5 7545U and Windows 11 25H2. My Xbox Wireless Adapter works normally on my main PC, but on this mini PC Windows detects it in Device Manager and reports that it is working properly. However, pressing the adapter's pairing button produces no LED activity at all.
I've tested multiple USB-A ports, including the rear USB 2.0 ports, installed Windows and driver updates, reinstalled the adapter driver, disabled USB power management for the USB Root Hubs, and rebooted several times. The Xbox controller works correctly when connected by USB, and the wireless adapter works on another computer.
Has anyone run into this on a MINISFORUM or AMD-based mini PC? I'm looking for a fix, or a way to determine whether this is a driver, USB compatibility, or firmware issue.

Try fully resetting the adapter: unplug it, shut the mini PC down completely, wait a minute, then reconnect the adapter after Windows starts again. Sometimes the device is enumerated correctly but its pairing hardware does not initialize until it gets a complete power reset.
Since you’ve already tested several ports, including the rear USB 2.0 ones, this probably isn’t just a USB 3.x interference issue. I’d remove the adapter from Device Manager, select the option to delete its driver if available, shut down the system, then install the current Xbox Wireless Adapter driver again after booting. If the LED still never comes on while the adapter works elsewhere, a mini-PC USB compatibility or firmware problem is more likely than the controller itself.
I tested the rear USB 2.0 ports as well, but the adapter still has no LED activity. I’m starting to suspect that the driver installation is corrupted, so I’ll try removing it completely and reinstalling it after a shutdown.
