But what about the ftdi device? I've managed to hang the system
with an ftdi based device as well. It is true that I sit with a
pl2303 device plugged in, but I then hotplug an ftdi device and
get the same crash. Can the pl2303 driver be making nonsense just
by sitting there while a ftdi driver is plugged-unplugged?
