Jul 12, 2011  Just for the records, i could successfully install the driver and use the USB-Serial adapter on Mac OS v10.8.2 (Mountain Lion). The only difference from the tutorial is that i had to alter GateKeeper configurations so a ‘non-signed’ driver could be installed.

Differences in Driver API

For most of these operating systems two types of driver are available: Virtual COM Port (VCP) drivers and direct (D2XX) drivers. The VCP driver emulates a standard PC serial port such that the USB device may be communicated with as a standard RS232 device. The D2XX driver allows direct access to a USB device via a DLL interface.

To locate the drivers you want to install for a device, select which of the driver types you wish to use (VCPor D2XX) and then locate the appropriate operating systems. With the exception of Windows 98 and Windows ME, all devices are supported in each driver package.

If a VCP driver is required for Android please refer to the following application note: TN 132 Adding FTDI Devices VCP Driver Support to Android

D3XX

D3XX drivers are only suitable for FTDI's Superspeed USB bridge services (e.g. FT60x series).
