Rock Endpoint over USB

Trying to use my NUC Rock as both Core and Endpoint. Endpoint will be connected over USB to USB DAC in my Hegel Rost. Problem is I don’t see any USB option to enable (lots of HDMI options but no USB). See attached:

.

Suggestions?

I’m pretty sure once you connect your DAC and power it up you will see which port it is connected to and it will be a USB port.

Hope you’re right! Waiting for my USB cable which will be here in a couple of days…will know then.

Hi @John_Mesberg,

Scott’s answer above is correct:

Once a Linux compatible USB device is connected via USB and powered on, it will appear as an option to enable. Before that, no USB options are shown.

HDMI works a little differently and those zones always appear here.

Thank you both.

Can these be turned off - if you are only using ROCK as a headless server and don’t require an Endpoints from the NUC?

You should be able to switch unwanted resources like sound cards and potentially HDMI in bios on a well specified motherboard. I presume that as a premium product you can do the same on a NUC.

Yes you can turn off all un-needed ports in the bios.

Disabling HDMI seems like a bad idea - if you ever want to see your BIOS again.

I don’t recall that option on a Nuc or any other motherboard without at least a slot for a graphics card

Even if you can disable the Hdmi it’s not going to be applicable in the setup bios options or there would as noted be no way to display anything in settings. Only after boot up OS.

This is very true.

As ROCK is a headless os and after installation Hdmi video is not needed, it has no ssh access either, only the web GUI. Audio is supported.

Ropieee on RPi is headless too…diet pi is not but ssh access is supported too.

Most other OS’s (windows, Mac etc) don’t like having no Video option, but don’t have to have a monitor connected top operate as a server for apps.

I have HDMI disabled on my MOCK build and it still displays but the 4 HDMI options are now gone from the enable output display. My presumption is that the option only disables HDMI audio. It is good to not have your screen cluttered with options you may never use.

According to the Help page above, if disabled, then video still works, disabling only audio … so possibly could work???
