Meilhaus Electronic Port Devices Driver

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.

But when I install Olivetti driver for that model printer Driver before ending driver ask you to physical connect USB to your printer and only in that case windows create virtual printer port USB001. If I continue without physical connection and later try to add printer I do not have virtual printer port USB001.

The Device Install Kit download site does not provide access to all Emerson Process Management device files. Device files distributed on DeltaV and AMS Device Manager release media are not duplicated for download from this site. No third-party device driver is required. Notify Meilhaus Electronic immediately by phone, fax, or e-mail. And connect the USB cable to a USB port. Dear Linux-serial team Meilhaus (PCI ID: 0x1402) ME90xx, ME91xx and ME93xx support added. The are RS232 and RS422/485 PCI serial boards. This patch was tested on x86 and x8664 machines.


Windows

(Manufacturer’s Chinese Info Link)

  1. Download the Windows CH340 Driver
  2. Unzip the file
  3. Run the installer which you unzipped
  4. 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.

Older Windows Driver Version and Instructions

  1. Download the Windows CH340 Driver
  2. Unzip the folder.
  3. If you are running a 64Bit Windows: – run the SETUP_64.EXE installer.
  4. If you are running a 32Bit Windows: – run the SETUP_32.EXE installer.
  5. If you don’t know, try the 64 bit and if it doesn’t work, the 32 bit.
  6. 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.

Meilhaus Electronic Port Devices Driver Updater

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`
