I get no USB devices recognised when I insert them any more, which
I think is pretty major. I suspect it has something to do with this ?

It looks like every port on my laptop is powered down, as I can't
even charge devices with it.

I tried running powertop, which noted autosuspend for the usb controllers
was 'good'. I flipped them to 'bad', but it made no difference.

What can I do to debug this ?
