Here are the results of the dutch jury ;-)

[    2.537109] HS USB OTG: no transceiver configured
[    2.542541] musb-hdrc musb-hdrc.0.auto: musb_init_controller failed 
with status -517
[    2.542541] platform musb-hdrc.0.auto: Driver musb-hdrc requests 
probe deferral

I am surely missing something here. Either in device tree or .config.
