I can not get the Stellaris USB Bulk Example to work on EK-TM4C123GXL launch Pad to work. I tried usb_dev_bulk codes from TivaWare_C_Series-1.1 and TivaWare_C_Series-2.1.0.12573. I am using Code Composer Studio 6.0. The error code is 1167 (The device is not connected).
The same application (Tiva C launch pad programmed with usb_dev_buld codes) works with Stellaris USB Bulk Example that I down loaded 12/16/2013.
