Hi Leon,

We do not have any USB to USB bridge controllers. 

There is one alternative, you can try to create a master slave setup of two FX3's to create a USB to USB bridge. You can find the details in the given link.

Maybe you could create the camera solution with singe FX3 with the UVC+HID interface.

Hi Leon,

Infineon has two USB controllers, FX3 and CX3.

FX3 gives USB support to any devices through its GPIF block, (no MIPI interface)
https://www.infineon.com/cms/en/product/universal-serial-bus-usb-power-delivery-controller/periphera...

CX3 specifically gives USB support to image sensors having MIPI interfaces.

Please let us know the image sensor interface at your end.

You can look through the dsrc.c (descriptor) file in the project attached in the below link for a UVC + HID interface.

Dear AliAsgar,

Thanks for your timely reply.

I have used FX3 in our previous product, the video interface is BT1120, and it is a composite usb device(UVC+HID), when the button is pressed, the camera send a ascii to the computer, and it works well.

Now we are planning to develop a new product,  the output of our new camera solution is USB, but it can't be modified to composite device, it just as UVC device, so I want to know whether has a USB controller that can connect to a UVC device and  expand to a composite device.

 

Thanks and best regards.

Leon.
