When starting, I get the following error, each controller is connected to the board to a different USB 2.0 with different cables, the swirtch of the floe controller is in position 1, the other just in case I put it in position 2 , but I still get the error, if I disconnect the second controller and leave the board connected only the year does not give error but of course, I can not control the case fan, to see if someone can tell me what I'm doing wrong.
