I was using an USB hub which did not cause problems previously but I
don't thing the power supply on it is very good so that might be the
problem.

Thanks for looking into this. I did not get to looking at the new
feature patches yet and the basic functionality makes quite a bit of
difference for the Olinuxino.
BTW the A20X IRQ enums seem to be numbered to match the bit position
in the register, including the extra effort to assign the value after
the gap - except for the last 4 which are 1 off due to the unused bit
before the GPIO IRQs.
Thanks
