Hi, I'm having a problem running the usb hid mouse device demo, using mqx 3.8.1, using TWR-K60N512. I tried with mqx 3.7 too and got the same error: "Device could not be initialized". I tried with the default jumper configuration, also with J6 in pins 1-2, and clock in serial to 50, as is showed in the manual, same error.
Now it is set like in those pictures, except that I have jumpers in all J5 pins:
I tried with windows XP and 7, different usb ports, reinstalled driver, changed elevator sockets, nothing changes.
Do you believe that could be a jumper configuration or the board is damaged?
Also, what is the purpose of jumper J4 in serial module?
