USB 3 power negotiation

Does anyone know if the USB3-HUB3ME automatically negotiates for USB3 900mA power when it connects to a USB 3 port?

Hello Ryan,

Thanks for reaching out on our forums with this question! As for the answer to your question, it depends on the device connected. When a device is connected, it will communicate with the port it was connected to and work with the host (the computer) to determine how much power it needs, and it all happens automatically. So if a device was connected to the hub that requires 900mA of power, it should get that amount when connected assuming the hub is connected to a USB 3.0 port.

Hope this information helps, but let us know if you have any additional questions!
