Thanks for testing this.

I'm not sure if I have a Lime (I might do, will need to look). I was
testing sunxi on a pcduino3 but USB does not work on that for reasons
I was looking into (it just says lowlevel init failure due to moving
to driver model for GPIO).

I will take a look. In the meantime, which commit breaks this? I could
perhaps issue a pull for commits up to that point to reduce the load.

Simon
