The only problem with it, is that, it reload the latest driver when you plug the device on a never used USB port. So, if you change place of connection, you should manually set the driver to 3.3, but you have to do that only the first time you used this port. Next time, the driver remain to 3.3 and never upgrade to 3.6. If drivers were not downloaded automatically by Windows Update, use Device Manager to refresh the driver from Windows Update, or contact the device manufacturer. I’m Moli, your virtual agent. I can help with Moto phone issues. Select Update Driver. If Windows doesn't find a new driver, you can try looking for one on the device manufacturer's website and follow their instructions. Reinstall the device driver. In the search box on the taskbar, enter device manager, then select Device Manager. Right-click (or press and hold) the name of the device, and select Uninstall.

Macintosh

(Manufacturer’s Chinese Info Link)

The following github has up to day pkg files for 1.3, 1.4 and 1.5 at time of writing, thanks to Joshua Wallis for bringing this to my attention…

Direct Download Links (from the github repo above):

See the github link above for installation instructions if you need them.

Previous macinstosh downloads if the above doesn’t work for you…

(V1.3) Download the CH340 Macintosh Signed Driver for Mavericks (10.9), Yosemite (10.10) and El Capitan (10.11) and Sierra (10.12)

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.

OSX Sierra (10.12) Note

A kindly user, Maarten Segers reports

FYI, the driver documented here WILL crash on OSX Sierra.

Make sure to use this one instead: https://github.com/MPParsley/ch340g-ch34g-ch34x-mac-os-x-driver

I can personally not test on MacOS and can not vouch for the above drivers at github, but there you go.

See uninstalling information at the bottom of the page if the driver causes problems for you.

Here is an older version of the Mac driver, NOT FOR 10.12 Sierra

(V1.0) Download the CH340 Macintosh Signed Driver for Mavericks (10.9), Yosemite (10.10) and El Capitan (10.11)

Linux

(Manufacturer’s Chinese Info Link)

Drivers are almost certainly built into your Linux kernel already and it will probably just work as soon as you plug it in. If not you can download the Linux CH340 Driver (but I’d recommend just upgrading your Linux install so that you get the “built in” one).

Uninstalling From Macinstosh

A couple of Mac users have said “the driver crashes my mac Sierra how do I uninstall”.

Firstly regards the crash make sure you installed the 1.3 version of the driver, not the old one. You could download it directly from the Manufacturers Website in case they have issued an update since I wrote this page.

Secondly a quick google search reveals that this is how you uninstall:

  1. Open a terminal and type: cd /Library/Extensions/
  2. Verify that the .kext file is present: ls | grep usbserial.kext
  3. Output should be: usbserial.kext
  4. Then type: sudo rm -R usbserial.kext
  5. Verify that the .kext file has been removed: ls | grep usbserial.kext
  6. Output should be empty.
  7. After you should remove the files stored in receipts folder: cd /private/var/db/receipts/
  8. Find the enties: ls | grep usbserial*
  9. Output should be: codebender.cc.ch34xinstaller.usbserial.pkg.bom codebender.cc.ch34xinstaller.usbserial.pkg.plist
  10. Remove each one of the files of the above list: sudo rm -r filename`
