usb_control_msg() is not exported as such to user space.
Which api to user space does it use? The input device or
usbfs?
Additionally which interface and endpoint is used? If it is a
vendor specific request to ep0, then the answer is no, it cannot
be done. Ep0 must be protected. You must write an ioctl kernel handler.
