I think we want to support frimware loading from userspace, and then the
userspace tool will need a means to let the driver know that it can
start using the device.

I thought reusing this ioctl could preserve compatibility with tools
used prior to 2.6.10.  Besides it was already mostly there, so I needed
less coding ;)

A sysfs attribute in the usb device directory?
