TUSB4020BPHPEVM: PWRCTL1/2 feature on windows 10 GUI

Part Number: TUSB4020BPHPEVM

I'm experimenting with the TUSB4020BPHPEVM Evaluation Module and I am wondering if there is a way to utilize the PWRCTL1 and PWRCTL2 features of this IC on windows 10. Is there are a way to toggle these pins via a windows 10 GUI as well as is there any API such that the same action can be performed via python?

  • Hi Nicholas,

    The PWRCTLx pins are controlled by the USB host controller using USB commands.  We do not have a utility that can be used to override the USB host controller.

    You can check the USB 2.0 specification (downloadable from usb.org) and search on "PORT_POWER" to see the conditions where the host sets and clears port power.

    Regards,
