I imported the example usb_host_msc code into code composer and have been running it on an EK-TM4C1294XL board using the ICDI interface. The example is from TivaWare_C_Series-2.1.0.12573/examples/boards/ek-tm4c1294xl/usb_host_msc.
I inserted a usb stick into the board and it does not recognize that it has been plugged in. The callback function is not called and the serial port reports "NODEV" at the prompt and a "not ready" message if I type "ls" at the prompt. I tried using a different board and a different usb stick with the same results. I also tried using both the example that I compiled and just burning the actual binary that came in the example with the same result.
There has to be some step that I am missing. Is there a jumper that I need to set or something else not in the instructions? I am following the instructions in "http://processors.wiki.ti.com/index.php/CLP_USB_Host".
