Can I send a USB control request in user mode ?

    I want to send a vendor control request to my own usb device from user mode.
    I found IOCTL_USB_USER_REQUEST with USBUSER_OP_SEND_RAW_COMMAND allows me to
    do so, but the root USB hub has to be disabled.
    I don't understand what does it mean "to disable USB root hub". Disabling
    USB hub device by device manager ? or something else ?

    Thanks for input.

    I was wondering if you ever got a response for this? I'm looking to do the same thing to my device as well?

    Thanks
