I don't think anything is needed for this.  Can't you do user-space loading
as follows:

(1) use usbfs to unbind the kernel module from the device
(2) upload the firmware
(3) use usbfs to rebind the kernel module to the device.

In the module's probe routine it will (hopefully) detect that the device is
already initialized, and not try to upload the firmware itself.  No ioctl needed.
