FTDI driver causing crash?

FTDI driver causing crash?
« on: June 09, 2013, 10:17:46 PM »
Just wondering if anyone else has seen this or if it was an isolated incident...

I was messing around with my TinyDuino, just toying with a few simple sketches and the led board. Everything worked fine until I unplugged it from the USB cable, which triggered an instant kernel panic / system crash in OS X. The FTDI driver was right at the top of the crash report when I restarted.

I had been playing with my TinyLily too prior to this (which uses same driver and same settings), and didn't have any trouble upon disconnecting that one. I've also been doing a fair amount of tinkering with both my Arduino as well as my Mojo FPGA with no stability problems.

Is this maybe just a rare bug in the FTDI driver? If it is semi-common then I will need to be more careful about when I tinker with these boards so I don't lose any real work when it takes down my other software.

I had the same thing happen! Thought it may have been because I didn't restart before installing the drivers, but then I tried the same thing on my work computer and there was no issue.

I'm running a MBP (circa 2006) on 10.6.8.

In looking at the Arduino forum, it seems to be somewhat common on a Mac when unplugging an Arduino.  I'd suspect an issue with the FTDI driver, although it doesn't look like the problem has been solved:

If you have the serial monitor open, I'd definitely recommend closing that before unplugging.  Hope this gets fixed soon!
