TUSB2077A: Individual port power control from host side

Part Number: TUSB2077A


Hello, we need to design a customized hub using this part and we wonder if we could get control of to the PWRONx pins from the host side manually. That means the possibility of turning off/on the power of each port.

The host OS is Linux. Maybe uhubctl utility will do the job? 

Thank you.

    Hi Manuel,

    The hub will respond to the commands from the host including the set port power commands.  Typically generic USB hub drivers set all the ports to power on/off at the same time.  TI does not have any utilities that will allow the USB host to set the port power on/off individually.
