We found out that there was a problem with our hardware design!
But first, here is the VBUS measureme

I am using an i.MX6Q embedded board, acting as a (ethernet) gadget with
RNDIS function, connected over an USB OTG cable to a PC.
Most of the time it works fine, but in some mysterious circumstances,
a kernel panic occurs, just after attaching the OTG cable, connecting it
to the other machine:
