OB not recognizing both AR & A4 in Live

I’m trying to run both an AR and A4 in Live with OB on a new PC running Win10.

AR or A4 work like a charm with OB in Live.

But when I try to run both together, the A4 HW is not recognized by the plug-in.

the plug in screen says in the bottom left-hand corner:

“Attempting to auto-select device. Please make sure your device is connected and powered on”

If I boot without the AR turned on, then A4 plug-in works, but then the AR will get the error message.

I have set up the outputs in the OB control panel before launching Live. I have both connected to an Overhub. I’ve tripled checked the USB setting on the HWs to make sure then are set to OB mode.

What am I missing?

Same thig is happening to me…sometimes it Works and other doesnt…frustrating…
