Support Forum » There's no cu.PL2303-0000211A file present in /dev directory

Using Mac USB after AVR install. I'm looking in /dev for the cu.PL2303-0000211A file and there's nothing even remotely like it, just a couple of bluetooth things. There's nothing with "USB" in the name - mostly ttyxxx and ptyxx stuff. Is there another /dev somewhere else? The USB - serial device IS showing up under system info when plugged in as:
I've installed AVR MacPack (twice) and I changed to gcc4. |

Oh, and I just re-installed the USD-serial driver package. Still no luck. |

OK - I went to Prolific's website (http://www.prolific.com.tw/eng/downloads.asp?ID=31) and downloaded/installed the latest driver (about 2 years younger than the NerdKits one) and I now have a cu.usbserial and a tty.usbserial file in my /dev folder (NOTE: These files only show up when the cable is connected - not sure why that is, but moving on....) I can't test it with the temp sensor kit until tomorrow. Update to follow. BTW, OS X Lion wanted to configure this cable as a new modem. I just told it to ignore it as a network device. I'm not sure I want it to try to handshake to my MCU or not. We'll see. |

Success. The new driver from Prolific loaded a "tty.usbserial" file in my /dev folder, and that's what I pointed the makefile to and everything works. I should point out that the Mac sees the serial cable as a modem and will ask you to configure it as such. I just left mine as "Not configured" and it's apparently not a problem. |

Thanks. I had the same problem, it did not even appear when plugged in, except I did have a COM 7 port already there. I have the most recent macbook air for reference. The chip displayed the initialload script after programming so it was successful. The new driver was necessary from prolific. |

This approach worked perfectly. Was able to download and install the appropriate USB drivers, also had to download a developer program for the Mac, modified the initialload.c file to experiment a bit, and voila! Everything worked and the LCD screen was modified as I had programmed. Thanks for the link to Prolific. Now onto the temp sensor, bought a servo motor yesterday, and eventually, to thrust vector control! |

I'm on Mac 10.11.6 and these instructions still work (original manual's instructions did not). |

Did you know that you can adjust most wire strippers to make it easier to strip insulation faster? Learn more...
