I have to mention that by default, I have setup FTDI driver to be picked up by osx and after a restart, the FTDI driver infact shows up.
This happened couple times before, but I managed to get it working by unload and loading the FTDI driver. I will be able to program the board but the serial port doesn’t show up in the /dev/tty.* The interesting thing is that when I unload the FTDI driver and load apple driver using the following command: sudo kextutil -b -p AppleUSBEFTDI-6010-1 Įrror: unable to open ftdi device with vid 0403, pid 6010, description 'Dual RS232-HS', serial '*' at bus location '*'īut at the same time, in another terminal window, I am able to see print outs of my previous program being running on the board (I can see tty.usbserial-00001014B). Now when ever I try to program my board, I am getting the following error: Error: libusb_claim_interface() failed with LIBUSB_ERROR_ACCESS.
I was working just fine with the board (e.g I was able to program and debug the board), until this afternoon. It is now couple of times that I am running into this problem.
