Bug in serial uploading

I am using a CH341 USB-to-ttl module on OS X. Because the path of serial port includes spaces, like “tty.wch ch341 usb=> RS232 1d120”, while uploading, avrdude recognizes it as “tty.wch”.


  • Arduino: 1.5.6-r2
  • OS: OS X 10.9.4


I don't see how this is an Arduino problem. Complain to the author of the ch340 USB driver. "tty.wch ch341 usb=> RS232 1d120" is an amazingly bad choice of name for a unix-like file!
