Topic: OSX Kernel Panic on unplugging USB (Read 2195 times) previous topic - next topic


If I unplug the USB cable while the serial monitor window is open I get a kernel panic - not always, but mostly.  Looks like the FTDI driver.

Any thoughts on stopping this happening would be much appreciated.

Here's the start of the crash report
