Can we use USB 3.0 and USB 2.0 at a time

[Anonymous]

Hi,

I am using CX3 controller in our project. I have one query regarding USB 3.0.

CX3 supports USB 3.0. It is also support USB 2.0. So, my question is "Can we able to use USB 3.0 and USB 2.0 at a time?"

For Example : I have a CX3 development board which support USB 3.0. So, If we connect that device to our laptop/PC (which support USB 3.0) then I want to do video streaming on TX line of USB 3.0 and send some information over D+/D- line of USB 2.0 at a same time.

So, Is it possible?

If it's not possible then what is the work around to send video and data on the USB port.

Thanks,

Amit

Hi Amit,

In your case, the video data will be sent to PC via USB3.0 path. USB2.0 is not available at the same time.
