the tmk_core chibios protocol_pre_task does not
process any usb events when the host is in suspend.
I think there is a race condition where the usb_event_queue_task
will not be processed depending on when usb goes to sleep.
so we may fall into the
while (USB_DRIVER.state == USB_SUSPENDED) {
which comes directly from the hardware interrupt.
and never process pending events in
usb_event_queue_task();
