    wireless headset


    Win7 Home Premium,x64 SP1
    Lenovo B570 laptop
    Logitech h750

    I don't have a problem. I am just trying to understand how things work; so I would like a technical explanation.

    I have been using the wireless headset via the same USB port every time until now. The drivers for the headset were loaded by Windows the first time only. The USB port I normally use was occupied; so I used a different one. When I plugged the dongle in, Windows displayed a message stating the the driver was being loaded.

    I explored device driver> properties to view information about the Universal Serial Bus controllers. Trying to read between the lines, here is what I think happens. Please make any necessary corrections to give me the proper understanding.

    The USB port I had been using had a specific hub# and port# connection where the device driver was loaded. When I plugged into a different USB port, the hub# and port# connection was different. Windows did not find the driver for this hub# and port # connection for the device. This prompted loading a device driver specific to the new connection.

    Am I missing anything?

    Thanks for your replies.

    Sounds about right, and the same will happen with any USB device (keyboard, mouse, etc) when plugged into a different USB port.

    I think you will also find that it isn't really loading a same driver over and over again when plugged into a different port, but more along the lines of registering the device/driver for that port using the existing driver.

    stormy13,

    Thanks for the reply. I have additional questions about the USB architecture. I will; start a new thread because it strays way off the course of this topic.
