Yes the pl2303 driver is a bit flakey in older release. 10.1 will hopefully have that fixed. Or just don't hotplug it. -Andi

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? - -- Steve Williams "The woods are lovely, dark and deep. steve at ..........
