Review on Douk Audio U2 PRO XMOS XU208 Digital Interface - USB To TOSLINK/Coaxial/Optical/HDMI IIS Adapter For DAC, Preamp & Amplifier | PCM & DSD256 Support by Tony Cole

To get the best out of it, connect only the B-type USB to a non-shared UBS-3 input. While this device does not require USB-3, connecting it to USB-2 will require you to connect a second USB-2 for extra power. When connecting to a 1-Amp USB-3, there is no need to use the power USB cable, which tends to disconnect and cause sound to drop.Also, do not use WASAPI (even). Use only WASAPI (push), as "event" causes sync issues when HD audio stream is present (above 48kHz).Overall it's a good and cheap digital audio converter solution. No drivers are required in Windows 10 or 11, but it will also add an unknown device, which you may ignore.
