USB port power off

[Gramps3165]

I use an external DAC as a digital bridge connected to my Ultras USB port. The DAC stays on all the time as it’s being fed power from the USB port.
Is it possible to add a feature to cut the power output from the USB port?

Thanks in advance

Instead of investing (wasting) a lot of resources in the useless VU-Meter, it would be better to finally de-energize the USB when the Ultra is off, or in standby - this way the DAC would also turn off automatically.

And yet those who don't use a usb dac might have a different opinion.

The original request, far less offensively written, explicitly asked to add this as a feature, which I understand as a switchable option.

That would be OK with me, but I certainly don't need this, so it would be "useless" and a "waste of resources" for me.

Please explain to me why the others don't want that. What is the point of keeping the USB port active if the Ultra itself is switched off?
"switchable" would be perfect.

I don't think that I have to justify to you why the current implementation makes sense, but here's a short hint: The WiiM Ultra, WiiM Amp and WiiM Amp Pro implement a fully featured media server that is exposed over the network. When I have a USB storage device attached, the WiiM might appear to be in "standby" or "off" (and in fact, it might be in a lower power state), but other endpoints in my network may be accessing the music hosted by said media server.

Thanks for the explanation, by the way, I didn't mean to come across as aggressive. In my use case, this implementation makes no sense, as I have all media files on a Roon server - in your case, of course, it looks different. That's why I think there should be a switchable option. Perhaps even the option, or a combination with power off/standby, that when an output, e.g. coax, is selected, the USB port switches off.
