Hi,
in kernel 3.4 USB doesn't work anymore in Visstrim_M10 board. It is
based on an i.MX27 chip and this is the log I get when connecting an
UVC webcam:

What I find out is that this worked properly in kernel 3.0 and stopped
working in 3.1. Has anybody found something similar with an i.MX27
based board?
Regards.
