Arduinos behind a hub

Projects Networking, Protocols, and Devices

Hello Everybody

I intend to operate several Arduinos on a powered USB hub.
The hub is to serve as common power supply but besides that I would like to be able to listen to the Arduinos' serial output.

I did read about ths USB specifications but couldn't find an answer to my questions which are:

How do I address each Arduino's serial interface?

Will each have their own COM port or will they all talk over the same port, potentially interfering with each other?

Can I address each Arduino from the IDE and hence program them via the USB hub.

I'd appreciate any insights you might have for me

Each arduino attached to the USB hub will have a virtual com port established for it on the pc (windows). You can open the arduino IDE and communicate with a specific arduino by selecting its assigned com port in the IDE tools. To communicate with a second arduino open a second instance of the IDE and select the appropriate comport in tools. Note that you have different boards, the appropriate board selection will need to be selected in the IDE.

Great - thanks a lot!
