Comment 20 for bug 1697395

@Kai-Heng: How do I unbind/bind all devices? Never did this before :/

echo "0000:00:1d.6" > /sys/bus/pci/drivers/pcieport/unbind

Seems to unbind all usb devices, at least they stop working :D ... but

echo "0000:00:1d.6" > /sys/bus/pci/drivers/pcieport/bind

has no effect.
