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;)
fractalbc already did a good job how it seams:https://github.com/fractalbc/cgminer
Id also be up for this tbh. Fractal BC's code base is great, but its still not stable! Im sure the community as a whole could donate some to you for testing as so many people bought them and they don't worj properly !
