But i am not on Hight Sierra i am on sierra ...? Maybe this is the problem ?

Yes, maybe a power issue. Make sure you have connected a power cable to the PCI-e card internally.

The power is well connected ... maybe i should try on my Win partition ?

I believe Sierra had support already. Make sure you are powering the USB card correctly.

What do you see in System Information > USB?

The problem is my audio card is powered thru the cable and the computer... no dedicated power ..

If you have already connected the following to your power supply, I don't know what else you can do to add power.

Yes, please try and see if Windows sees your device.

This is not a Thunderbolt card. It is a USB 3.1 gen 2 card.

You must make sure the devices you plug in it are USB devices, not Thunderbolt.
