USB Serial not working on OS X 10.9.5
According to the Serial port manual, the serial port of the LPC4088 Quickstart Board should show up on the Mac without installing any driver. It should be found somewhere at /dev/tty*.
If I compare the list of devices in /dev/ before and after connecting the Quickstart Board, there is no difference. Neither does the board show up as a memory stick, nor can I connect it to Windows on Parallels.
dmesg shows the following output after connecting the Board:

Does anyone have any hints?

Can you update the interface firmware on the device? http://developer.mbed.org/users/embeddedartists/notebook/lpc4088-updating-the-cmsis-dap-interface/
To do this on a Mac you'll need to use terminal and something like
>cp -X <path to bin> <path to device>
