write the resume-bit of the command-register. This will drive the non-idle-state on the
USB for 3 ms, host will start a wakeup-procedure.

Device disconnecting
Either our device is bus- or self-powered. In the case of being bus-powered, every time
the device is disconnected from the bus, the power supply will break down and a re-
plugging will restart with a reset of the entire chip.
In case of a self-powered device, if there is a disconnection from the USB, the logic of
the usbblk must be reset. There must be external logic added to provide the detection of
a disconnection. If SW detects a dis- and reconnection, it must disable all the epec
channels and reset the whole usbblk by writing into the usbd_cmd_reset register. After
de-asserting the reset, the whole configuration process (with writing of the configurator)
must be redone.
