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.
Windows

(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.
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

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

USB 2.0 on Windows XP and 2000
There are many reasons why problems with USB devices can occur. Keep in mind that USB Controllers are small pieces of hardware that allow your computer to operate USB connections. These Controllers need software drivers to operate properly. That’s why your first step is to check that you have the latest USB 2.0 drivers on your system. Dye paintball.
Download Coachlab 2 Port Devices Driver Updater
Start by opening Windows Explorer and right-clicking on My Computer. Click the Hardware tab, followed by the Device Manager Button. Towards the bottom of the list you should see a heading ‘Universal Serial Bus Controllers.’ Click the small plus sign next to it. This menu will expand to reveal one or more listings. To see if you have USB 2.0, look for a line that says ‘USB2 Enhanced Controller.’ The exact entry will vary slightly and don’t confuse it with other entries that may simply list ‘USB Universal Controller’. See the screenshot to the below for an example of how it may look. Note that there are no yellow exclamation points next to the entries – the yellow exclamations, indicate a problem with the device.

OK, what if you look down the USB list and there is no entry with 'USB2 Enhanced Controller'? This generally means that you do not have the USB 2.0 driver installed. There are two steps you need to follow. Firstly you must ensure that you have installed either Windows XP Service Pack 3 or Windows 2000 Service Pack 4. Technically, XP users only need Windows XP Service Pack 1, but this would be risky as it leaves your system exposed to numerous security threats fixed with Service Pack 2.
Download Coachlab 2 Port Devices Driver
If needed, download and install the Service Pack, then restart your system. Go back to the Device Manager - as shown in the first paragraph - and check the status of your USB controllers. If the USB2 Enhanced Controller has appeared without the yellow symbol, you should be ready to use USB 2.0. If not, you will need the specific USB 2.0 driver for your system. There are only six manufacturers of USB 2.0 controllers: Acer Labs, Intel, NEC, SiS, VIA and nVidia (which may appear as 'Standard Controller'), but sometimes they are re-branded by other companies. In this case, you will need to find out which Controller is on your system and visit the manufacturers site for an update or special instructions. For example, if you have the Via USB Controller, you will need the Via USB 2.0 driver (you can download a copy here).
