I'm trying to use the Stellaris ICDI target interface on Mac OS but when I connect I get a 'cannot open USB device' error, what do I need to do to get this to work?
It could be that the device has been claimed by the Apple CDC device driver. Try running the following command from a terminal to unload the driver before you try to connect:
sudo kextunload /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBCDC.kext

Hello, I have the same problem, unloading the Kext, I only now get a "Cannot find device with VIP xxx PID xxx" like if the debugguer was not plugged, and the System Information application, correctly show it on the USB ports. I also have the same error with an Olimex OpenOCD USB device..
(For the Olimex device, I found, I had a FTDI driver that was causing the problem) but the Stellaris ICDI still not work :(
