3D Vision usb emitter init.

3D Vision was running quite well with my gtx1080 and acer monitor with buil-in emitter even the driver
complains a quadro card is needed.

Im trying a usb emitter with my new asus pg278qr monitor.The monitor toggles in 3d mode but the emitter is not initialised and blinking red.
xorg log: -> usb emitter request.
Seems to be a usb problem ?
Thanks, sorry for my english.
