In new IDE sometimes, the list of ports is not refreshed.
In my case it shows available port, but does not connect.
Even after removing USB cable, it still lists the port.
Restarting WebIDE does not change this, port is still listed.
Sometimes then disconnecting USB cable and connecting again helps.
Sometimes it needs an additional reset on Espruino.
Never had this problem with old version.
