If I try to connect via pure USB that connects to STM directly, nothing is found in system.
Is it that nothing is found, or that you don't have the drivers installed? Perhaps your board is different yet again and they've changed the pin that USB Disconnect is on.
There isn't an option to change the timeout - you'd have to download the Web IDE source and set it yourself.
Honestly, if you want to try compilation out - just get a proper Espruino board and try with that.
