Interrupted music playback when using USB isolator Intona 7055-B

Hello everyone,
I recently started using the USB 2.0 Hi-Speed Isolator from Intona. I often get the message that my DAC (Cayin CS-100DAC) is not connected to the RS 150B. After switching the two devices on and off several times, I can listen to music again and the signal transfer from the RS 150B to the DAC is established. Does anyone have a solution to the problem. The sound reproduction is audibly better via Intona USB-ISOLATOR.
Many thanks and best regards
Reza

Then you know where the problem comes from. I had the same issue with Audioquest.
No solution except, I don’t use it anymore - but of course it was on the Input - not with an external DAC.
Currently I’m happy with how the Rose RS+50 sounds - have not heard the B Version with the ESS.
