Hi, I refer "C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\firmware\uac_examples" to create a UAC device on FX3, and it can be recognized by Windows Device Manager.

I also wanted to check it on Linux - Ubuntu 18.04; However, I didn't find any change in "/dev/" or by command "dmesg"...

How could I check if UAC device exist on Linux?

PS. If I changed the FX3 image to UVC program and plugged into Linux PC, I can find v4l, video0 & video1 was listed in "/dev/". Therefore, I think the UVC can be recognized by Linux, but I cannot use this method to check UAC device.

Any help will be highly appreciated!

Solved by myself... I found the change in "/dev/snd".
