Interfaces over USB are "virtual com port" and the D2XX driver layer.

• based on the FTDI FT232H chip
• provides an easy way to get a USB2.0 Hi-Speed (480Mb/s) connection to your device
• operating modes: UART, BITBANG, FIFO, FT1248 MPSSE (= JTAG, I2C, SPI)
• IO pins CMOS 3V3 and 5V-tolerant
• fits a breadboard (DIP28 600mils)
• mini-B USB connector

Note! Check the required drivers and the FT_PROG utility on FTDI's website. For Linux, the open-source libftdi1 drivers are an alternative.
