Hello,
I have a custom board with TUSB4041I device, without i2c connected to it. The host is running Ubuntu 18.04.
I would like to disable port 2 of the hub. How it can be done? Is it possible to configure the hub from usb port?
Can i disable the port from linux usb driver?
Thanks
Boris

The USB host controllers can send commands(Clear Port Feature) to USB hubs to disable ports, but these USB commands would need to be generated by the host not the hub.
It is possible to configure the hub with disabled ports over I2C but this can only be done by setting Register 08h after the initial reset of the device, it is not intended to be configured real time.
Thanks
David
