HID: ACRUX - activate the device immediately after binding
This device does not tolerate delayed opening and goes into a coma if
we try to that. Ubuntu even has a crutch for udev that opened the device
upon seeing it for the first time, but it did not work if we happened to
boot with the device attached, since by the time userspace got around
opening the device it was too late. Let's start the device immediately
to deal with this issue.
