Other Parts Discussed in Thread: TUSB2046B

Hello,

I'm currently developing a project with the TUSB2046B.

I would like to know if it is possible to activate/deactivate any specific downstream port of this HUB via software command. If there is any command protocol that would give me the ability to do such.

Hi Rafael,

I am going to move this post over to the consumer and computing interface forum as they support the TUSB chip set.

Hello Rafael,

The TUSB2046B does not have a port disabled feature but can be commanded by the USB host to selectively suspend the downstream ports.

The USB selective suspend feature allows the hub driver to suspend an individual USB port without affecting the operation of the other USB ports on the hub.

The link below has more in-depth information about it.
