Neither of us have an antminer U1, no one is offering to give us some, and no one is pushing code to us to be accepted for those devices. So at this stage there is precisely zero progress and nothing on the horizon.
I'll donate one to you or kano or ... - which would be easier/cheaper to ship from germany;)
