Some interesting USB console behavior, I can't understand.

I helped Andrey change project to fix this.
1) In \Espruino\targets\linux\jshardware.c we cut function

bool jshSleep(JsSysTime timeUntilWake)  {
...
...
...
}

to

bool jshSleep(JsSysTime timeUntilWake) {
  return false;
}

2) In \Espruino\targets\mbed\jshardware.cpp

bool jshSleep(JsSysTime timeUntilWake) {
   __WFI(); // Wait for Interrupt
   return true;
}

to

bool jshSleep(JsSysTime timeUntilWake) {
   return true;
}

3) In \Espruino\targets\stm32\jshardware.c

bool jshSleep(JsSysTime timeUntilWake) {
...
...
...
}

to

bool jshSleep(JsSysTime timeUntilWake) {
   return true;
}

We have a working result. Thank you!
