Or for > that matter any other EP (like EP2 which is for interrupt). you're gonna have to add your own debugging messages to musb_g_rx(), musb_g_tx(), txstate() and rxstate() in the file drivers/usb/musb/musb_gadget.c > The debugs simply show no activity on EP0 (i.e it's in the idle state > and receiving > SOF markers from the host). for ep0 check musb_gadget_ep0.c > Also, I'm a little confused about MUSB and TUSB!
