USB DAC Auto Suspend delay time

I just set up my first RPi endpoint, and it’s fabulous. Really impressed with how easy it was!

I have a rather unique situation where my USB DAC (a Wavelength Cosecant V3) doesn’t have a power switch. It powers on automatically when the USB port is active.

USB auto suspend does the job, but the default 2 second suspend time is too short. Is there any way to configure it? Ideally I’d want it to be about 15 minutes (the DAC has a tubed output so the purpose is to prevent the tube from burning all day).

Thanks,
Andy

Digging up an old topic here but plus one for me on this feature request. i.e a configurable suspend time for USB Suspend timeout.

I will be using a device that detects the Toslink output on my DAC and creates a 12V Trigger for controlling the AMP connected to the DAC. I want to avoid the AMP shutting down each time I pause the music.

An option would be a short or long option, short being the default timeout and long being 15 minutes.

I’d be happy to test and feedback.
