I'm seeing

[    2.190155] unable to find transceiver
[    2.190155] HS USB OTG: no transceiver configured
[    2.190155] musb-hdrc musb-hdrc.0.auto: musb_init_controller failed
with status -517
[    2.207458] platform musb-hdrc.0.auto: Driver musb-hdrc requests
probe deferral

on 4430sdp with v3.10-rc1. Does that mean that the musb-hdrc.0.auto was
indeed correct, and the new value of musb-hdrc.2.auto is not?

The musb-hdrc id is wrong on overo also.
