OpenOCD "configure: error: hidapi is required for the CMSIS-DAP" HIDAPI_LIBS

If you are trying to install OpenOCD with CMSIS-DAP support on Mac OS and having trouble, this Gist may be for you :)

This is the typical error if you specifically try to configure OpenOCD for CMSIS-DAP support

Hi All, Yesterday I got a FTDI (UART to USB) board from unknown manufacturer. I plugged in to the iMac and without a surprise, it was not working. I have tried all the possible combinations, but no luck. Then after some digging in Apple documentation and Google about kext, FTDI and related, I finally made it. Here are the steps:

  1. In order to disable the AppleUSBFTDI.kext extension (From Mac OS X 10.8 there is Apple driver implementation for the FTDI chip).
cd /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns
sudo mv AppleUSBFTDI.kext AppleUSBFTDI.disabled
