>Description:
dmesg is flooded with:
uhub7: port 4 reset failed
uhub7: port 3 reset failed
uhub7: port 4 reset failed

Sometimes my USB devices (builtin or plugged in) stop working.

See the dmesg below from seconds after booting. It has
USBVERBOSE and USD_DEBUG set -- otherwise it is GENERIC.
I also did "write usbdebug 0xffffffff"
