I am able to use the TWR-K60F120M with the TWR-SER, run the hid example, and get the mouse and keyboard to work just fine. However I need to run high speed USB with the TWR-SER2. I shunted J21 as instructed for high speed USB but it does not work. I can't even run the application. I tried changing BSP_USB_TWR_SER2 to 1 in twrk60f120m.h but that didn't help. Thanks for your help.
