hello, administrators.
I have a arduino compatible board that use the ch341 serial ic. and I make an extension js for scratch 2.0. It can run on Windows very pefect. But on Mac OSX(10.9.3) the scratch extension plugin on browser can't detect the serial port and the browser didn't open the window for choose serial port.
Through the terminal, i found the serial device: tty.wchusbserialfd120 and cu.wchusbserialfd120
How to solve it on My Mac?
Thanks.
