Mac OS, Linux driver for CH340K #3

ppeters · 2020-06-12T05:41:18Z

The CH340K has an unrecognized device ID on macOS Catalina, actually the ID is 1 lower than on a Wemos D1mini. Could you provide a driver for macOS like you did for microsoft windows?

johndoe71rus · 2020-06-16T18:29:53Z

try this http://www.wch-ic.com/products/CH340.html

i can't compile CH341SER_LINUX.ZIP for linux. device detect as
idVendor=1a86, idProduct=7522

inside ch340x.c
#define CH34x_VENDOR_ID 0x1A86
#define CH340_PRODUCT_ID 0x7523
#define CH341_PRODUCT_ID 0x5523

ppeters · 2020-06-22T21:03:04Z

I don't get the comment. The link mentioned above points to a page that shows many CH340 versions and has links to all kinds of CH341 drivers (windows, linux, mac) that do NOT support CH340K as far as I can see... The drivers I have downloaded (also the CH341SER_MAC.ZIP) supports vendor ID 0x1A86 and product ID 0x7523 but NOT product ID 0x7522

johndoe71rus · 2020-06-23T03:08:20Z

this is the best i could find. so you are lucky like me. I did not look inside windows and mac drivers. I could not build the linux driver. The next step would be to try to add product ID 0x7522. sometimes it’s enough.

ppeters · 2020-06-23T06:41:04Z

I appreciate the effort very much. I seem to be unable to find the driver's sources (that you have been able to find) to try and compile a new version... (preferably the mac version sources of course)

johndoe71rus · 2020-06-23T17:04:52Z

according to describe CH341SER_* does not support CH340K http://www.wch-ic.com/downloads/CH341SER_LINUX_ZIP.html
"CH340G，CH340T，CH340C，CH340E，CH340B，CH341A，CH341T，CH341B，CH341C，CH341U"
For linux they suggest source code. So we are unlucky.

ppeters · 2020-06-23T20:20:42Z

Ok johndoe71rus, thanks for your efforts. I guess we're at the mercy of Lilygo then. Let's hope they respond...

johndoe71rus · 2020-06-24T04:07:30Z

Can you change issue name to "Mac OS, Linux driver for CH340K".

I use tx,rx,gnd to connect PL2303 Serial Port to change firmware to NodeMCU. But onboard usb controller is convenient

johndoe71rus · 2020-07-01T03:52:39Z

for me work advice

manually load module ch341 and then enter:
sudo sh -c "echo 1a86 7522 > /sys/bus/usb-serial/drivers/ch341-uart/new_id"

try find the same for MacOS

ppeters · 2020-07-01T08:17:51Z

Ok, I’ll see if there is something similar on the Mac. Thanks a lot for hanging in there with me :-) !! Kind regards, Peter

elektro-wolle · 2020-09-23T09:28:51Z

I opened a support request at mac-usb-serial.com to include the new Product-Id (0x7522) into their drivers, but got no response. Neither per Mail nor twitter.

rmjjanssen1 · 2020-12-30T19:35:30Z

Hi,

Have the same issue here on Mac OS Mojave. Is a fix available?

elektro-wolle · 2020-12-31T13:39:07Z

@rmjjanssen1 I'm currently using a debian VirtualBox-Image to initially flash a esp-home/tasmota-image and using OTA-Updates for later installs.

geo777535 · 2021-02-04T17:38:45Z

I want to use this model (LILYGO-T-OI) as a wi-fi deauther , after installing the driver for uart (CH340K ) ,can i use ESP8266 Flasher install the firmware wi-fi deauther ?

johndoe71rus · 2021-02-05T04:04:51Z

I think yes. I am using nodemcu-pyflasher to flash my NodeMCU firmware. The basis of success is a working CH340K for exchange with a computer.

geo777535 · 2021-02-06T18:46:56Z

3 LEDs on the board What does everyone do? when it turns on when it turns off ? it is true, that if the board is turned on the red LED is constantly on How to turn it off ?

jbrepogmailcom · 2021-02-09T15:59:48Z

On my ubuntu, USB gets identified automatically as ID 1a86:7522 QinHeng Electronics USB Serial. Use watch lsusb

geo777535 · 2021-02-16T22:25:52Z

how many dbi of ceramic antenna module LILYGO-T-OI ?

algomusic · 2021-03-22T03:33:38Z

Disappointingly, there still seems to be no Mac USB driver support. I had to use a Windows box instead to program this board.

ppeters · 2021-03-22T22:21:12Z

Maybe we’re barking up the wrong tree. I guess it should be peanuts for Apple to extend their driver with a single new driver ID... Peter — Sent from IPhone

Works fine for me on mac OS 11.5.1 (macbook pro 2017) until i reenable System Integrity Protection. After that the driver is not available anymore.

eschwim · 2021-08-28T15:57:28Z

In case anyone else stumbles across this: I was running into the same problems with the new LilyGO T-OI Plus (the risc-based ESP-32C version), which also has the CH340K in it.

I only have a Mac to work with, so I thought I was stuck. However, it turns out that WinChipHead is super responsive to email. I asked them if they could rebuild their MacOS driver to support the CH340K and they did it the same day! I have installed it and confirmed that it correctly creates a serial device (at /dev/cu.wchusbserial1432220), where previous versions of the driver have not.

It looks like they don't have a download link available for the new version on their website yet, so I am linking to a gdrive folder containing the driver package that they emailed me: https://drive.google.com/file/d/1XY9kOZ1EUEC6M5IrDPSYzNRRJ1k6VkwL/view?usp=sharing (it is digitally signed, so you don't need to worry about disabling SIP).

Hope this helps someone else!

ppeters · 2021-08-30T14:22:02Z

Thanks @eric Schwimmer!!, this finally solved my issue… Kind regards, Peter

@eschwim Are you running Big Sur? Near the end of the installation, another app pops up asking to install additional drivers and it is not successful. I think it requires disabling SIP, but I am not sure if it is safe to do so or if it would continue to run after enabling SIP. Would you be able to check with the provider of this driver? Thanks!

eschwim · 2021-09-14T06:13:29Z

Yeap, running Big Sur, v11.5.1 (20G80).

My memory's not what it used to be, but from what ISTR the only popup I got during the install was in mandarin (which I can't read), and it had a single button that I just blind-clicked on and the installation finished.

Did you check out the "System Preferences -> Security & Privacy" config screen? There might be something under there that you need to allow before the driver install will succeed.

miloshev · 2021-09-17T06:48:59Z

Thank you very much for the driver. It works like a charm on BigSur 11.4 :)

19eighties · 2021-09-17T07:01:24Z

@eschwim, thanks for the additional info. I had to update my OS to the latest and now it works. I think I was on v11.1.

algomusic · 2021-09-18T00:29:04Z

@eschwim Thanks for following that up. BTW, I'm still running MacOS Mojave 10.14 and it worked for men(but that prob has less OS security barriers than v11).

Hello, everyone. The ch34xser New driver has been supported here: https://github.com/WCHSoftGroup/ch34xser_macos
Which supports all platforms(include Big Sur).

Also, the linux driver: https://github.com/WCHSoftGroup/ch341ser_linux

I guess there is no support for the new Apple M1 Macs yet?

3rwolff · 2022-01-27T20:45:03Z

Hello, I am on a MacBook Pro running macOS Mojace Version 10.14.6. I had the ESP32-CAM working yesterday but then installed the driver mentioned in this thread (CH34xVCPDriver_signed.pkg https://drive.google.com/file/d/1XY9kOZ1EUEC6M5IrDPSYzNRRJ1k6VkwL/view?usp=sharing trying to also get the TTGO-Camera chip to connect) and ever since then I am unable to get the ESP32-CAM to work anymore. My first instinct was to un-install this driver to see if that was causing the issue but I don't see any way to uninstall it.

The error message I get when I click "Upload" in my Arduino IDE is: "A fatal error occurred: Timed out waiting for packet header". I have the same board selected as when it worked yesterday (i.e. AI Thinker ESP32-CAM) and am using the same port ("dev/cu.wshusbserial14110" which is a usb port on a dongle that I have connected to the USBC port on my mac).

I am pretty stumped on what is causing this issue if anyone has any input it would be greatly appreciated. Thanks

3rwolff · 2022-01-27T21:23:05Z

I also tried following the uninstall instructions and then re-instal instructions here with no success https://github.com/WCHSoftGroup/ch34xser_macos

Hi @SuibianP !
No, I tested it on my M1 Pro 16", do you have issues in your M2? if so, try to navigate system settings to see if there is any warning or something asking for permissions, it might be that.

I can confirm that this driver is working (M1 Max, Ventura). Make sure you download newest version from GitHub and run dmg file.
When prompted that extension is blocked in the system, go to Privacy settings on a macOS and allow the extension to run.
