BluetoothDriver ver 188.8.131.52 seems to have caused the error.
When I changed to BluetoothDriver ver 184.108.40.206 the error no longer exists
Unknown usb device Device descriptor request failure code 43 Error The problem has been resolved.
Back when the Fall Creator's Update came out, we had all sorts of issues with BT. This was a MS issue. I am presuming the same goes for the Spring Creator's Update. Do the following:
1. Download latest WiFi and BT drivers fron Intel Download Center and copy onto NUC.
2. Disable internet access.
3. Totally uninstall the WiFi and BT drivers.
5. Install BT and then WiFi drivers.
6. Reboot and test.
Hope this helps,
