    Exactly. The kernel will by default get the device up and working. Any
    capabilities to be changed after it is working can be done by userspace
    with a "whitelist" type program that can properly tell the kernel that
    this specific device can be safely suspended.

    If you decide to do this in a small bash script, or in
    HAL/udevd/DeviceKit/whatever, it all doesn't matter to the kernel.

    thanks,
