Using Cypress FX2 to determine host power capabilities

[nburkitt]

Is it possible for the Cypress FX2 device (on a TE0630) to determine if a connected USB device is a Charging Downstream Port (CDP), Dedicated Charging Port (DCP), or Standard Downstream Port (SDP)? If so, can someone suggest where in the FX2 firmware to start looking?
Thanks,

Hello,

You can found FX2 firmware sources at https://github.com/Trenz-Electronic/TE-USB-Suite/tree/master/TE_USB_FX2.firmware
There is no CDP/DCP detection in current version

Hi Oleksandr.

Thanks for the reply. I have the FX2 firmware already - I'm hoping for some guidance on where in the firmware such a determination might be made. Or at least where to start looking without first becoming a USB expert.
Thanks again,
