TUSB8041A: could we enable/disable individual port?

TUSB8041A: Enable/Disable Port During Runtime.

Part Number: TUSB8041A

Hi,

Good day.

Our customer wants to enable/disable the ports during runtime, not boot, using SMBus. Would it be possible to do this? If yes, we will appreciate if you could help us. 

Thank you and have a great day. 


Regards,

Cedrick

    Hi Cedrick,

    No, this is not a capability of the hub.  Hubs are USB slave devices and will only turn on / off power to ports based on commands from the USB host.

    In addition, the TUSB8041A hubs can only enable / disable a port at power on reset - not during runtime.
