2 usb linux host or multiple devices to the ethernet

Other Parts Discussed in Thread: TUSB4020BI

Hi all,

I want to make a duckstation like usb to ethernet. I have 2 devices, not 1, in the usb port. I simply have 2 Raspberry Pi zeros.

Does anyone know how I can do this or does TI have a suitable chip recommendation?

This is my first time dealing with something like this, if you can help I'd appreciate it.

Best Regards,

Mehmet

    Hi Mehmet,

    This thread is for the Ethernet PHY group. We only deal with the ethernet PHY. This question is out of scope of our knowledge.

    Hi Mehmet.

    Our USB hubs like the TUSB4020BI or TUSB8020BI support connections from a single USB host port to two USB device ports.

    From your block diagram, it looks like you would have two USB hosts (Raspberry Pi) to a single device (USB to Ethernet).  In this case you wouldn't want both hosts controlling the device at the same time, so you could use a USB switch / mux but you would need control to change which host is accessing the device.
