(V1.0) Download the CH340 Macintosh Signed Driver for Mavericks (10.9), Yosemite (10.10) and El Capitan (10.11)ĭrivers are almost certainly built into your Linux kernel already and it will probably just work as soon as you plug it in. Here is an older version of the Mac driver, NOT FOR 10.12 Sierra See uninstalling information at the bottom of the page if the driver causes problems for you. I can personally not test on MacOS and can not vouch for the above drivers at github, but there you go. Inside the zip file you will find a PDF and a “pkg” file, short version, double click the pkg file, the PDF has some extra information.įYI, the driver documented here WILL crash on OSX Sierra.

In the Arduino IDE when the CH340 is connected you will see a COM Port in the Tools > Serial Port menu, the COM number for your device may vary depending on your system.The Linux kernel just doesn't seem to recognize the printer (almost as if hot-plugging isn't supported) unless it starts from a clean slate.Īdvice or better, a solution to this problem would be great, as I've torn enough of my hair out trying to resolve it.The CH340 chip is used by a number of Arduino compatible boards to provide USB connectivity, you may need to install a driver, don’t panic, it’s easier than falling off a log, and much less painful. Has anyone else had this issue? I don't believe it's even octoprints fault. I've tried taping off the power pin on the usb cable to see if i can just turn the printer off, then on to prevent having to keep unplugging the USB cable, but then I cannot connect to the printer at all, even via the aforementioned method. This is getting extremely frustrating, as every time I need to reboot octoprint, I have to go through this procedure and it's getting silly now. connect to octoprint (printer also shows via lsusb: Bus 001 Device 008: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter).To get my printer to connect to octoprint and to even show up via lsusb, I have to do the following: Raspberry pi b3 running latest version of octoprint.
