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.
If you are using MQX try this:
enable HS driver
#define USBCFG_DEFAULT_DEVICE_CONTROLLER (&_bsp_usb_dev_ehci0_if)
#define USBCFG_DEFAULT_HOST_CONTROLLER (&_bsp_usb_host_ehci0_if)
And rebuild libraries.
This works on the TWR-K70 , try it on the TWR-K60
Also, In the USB stack, you need to setup HIGH_SPEED_DEVICE to 1 in user_config.h in each USB stack project you want to test with TWR-SER2.
