This example application demonstrates using a USB Communications Device Class for hosting a FTDI FT232R device. I'm using FTDIs UB232R development module: http://apple.clickandbuild.com/cnb/shop/ftdichip?op=catalogue-products-null&prodCategoryID=58&title=UB232R Which has this FTDI chip: http://www.ftdichip.com/Products/ICs/FT232R.htm It has USB_CLASS_VEND_SPECIFIC (0xff) Interface Class. Other CDC drivers could also be added to this example in the future (ACM, Prolific,...). Howto: Copy files to StellarisWare folder Add usb_host_cdc project to workspace Add usbhcdc.c and usbhcdcftdi.c to usblib project. Recompile usblib. Upload to target. After device is enumerated it sends FTDI baudrate control transfer. Baudrate is set to 115200. When FTDI is connected to USB OTG it will send out "usb_host_cdc echo example" string. When device is ready everything FTDI receives on RX is send to TX (echo).
