Hi Wim.
I'm very glad to see you.
Martin, Wim listed almost all the devices that we tested.
I would like to add that the main two devices are XMOS and Amanero, which are now used in almost any DAC. Therefore, the devices that supports USBAUD2.SYS much more.
There is one caveat to the Amanero device: it must first be flashed with the latest version.
After that, the device will accept the standard UAC2 protocol and will be seen by the driver USBAUD2.SYS
The Amanero device, it is better to buy a licensed one, otherwise the firmware will not be available.
