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 -rfilename`
