-Instantiated USB components prevent devices from going to deep sleep due to USBPhy holding a deep sleep lock. It is possible to temporarily disable USB using `USBDevice::deinit()` to permit deep sleep. However, it is up to the user to make sure all the data transfers have concluded to avoid any data corruption. The USB host controls the enumeration process so it chooses when and how the device will be restored. Even if the device state is returned to what it was before the disconnect, the host PC software may not be where it left off - for example a serial port may need to be re-opended by the user.
