Hi Alsiro, Can you clarify a few things? - Have you run the bare-metal HID Keyboard example? The reason I askes is because your original thread was for the TI-RTOS based HID Keyboard. - Are you seeing the same issue if you modify the bare-metal HID Keyboard example? Please note the TivaWare version in TI-RTOS is much older than the latest TivaWare SDK which is version 2.2.0.295 although I doubt the version would make a difference as far as USB is concerned. - When you modified for the TI-RTOS example, did you rebuild the usblib.lib? I will suggest you use the bare-metal example as a starting point as it will be easier to debug as to take the TI-RTOS and its older version of the TivaWare out of the equation. - Can you clarify about your USB device? Is that a custom device that only a MISC class can work?
