Amplifier K7 not recognised under device manager

[Lello29]

Hi all, i searched everywhere but didn’t find anything. I own a fosi k7 and this is how it is shown under device manager
This appears to be due to the uac 2.0 connection because it disappears when I change it to uac 1.0.
The sound is working and I can see it under windows audio output. But I can’t see it under device manager (only under unknown devices)

I’ve tried everything to fix it: uninstalling, disabling the device, changing windows version, formatting windows, I have tried to use it with another pc. No matter what I do, it appears in DFU mode. I don’t think it is supposed to work like that, I can’t find any driver either. I need to know if I have a faulty unit or I have to download some software or driver somewhere.
I need help from the community
Thank you

I have the same issue.

I have the exact same issue. For whatever reason, Windows 11 does not recognize the K7 in UAC 2.0. I have tried to delete the drivers and have it re-install, but it just doesn't recognize any drivers as working with the device. I went to the support page, and there are no drivers for the K7. What the hell? Are there no drivers for Windows 11 at all?

I got a very fast response from FOSI, kudos to the fast response. If anyone else is interested, this was the solution:
