I got an used UMC202 (not the HD model) and t is not working in my PC (Windows 10 64bits) . After a few minutes, the audio just sop playing, I need to disconnect USB cable and connect again to have the audio back but after some minutes, it stops again.
I notice that there is a firmware upgrade in the website v1.12 and thought I could try to install it.
Downloaded and extract the files but when I run the file UMCAudioDfu.exe I got an error message : "The driver DLL required to access the device is missing"
I saw an older post with the same problem but his solution was to use an application installed with the driver called UMC Audio Firmware Upgrade. However, when I installed the driver, it not instlled this aplication, only the UMC Control Panel .
I am using the driver 4.38 file BEHRINGER_UMC_DriverSetup_v4.38.0
