[求助]在MacOS 10.14 Mojave下无法使用CH34x USB转串口

我先下载了1.5的驱动安装后,无法识别CH34x usb设备。后来看帖子https://github.com/adrianmihalko/ch340g-ch34g-ch34x-mac-os-x-driver,说在:Do not install if you have the current macOS Mojave 10.14 or later. 所以按照下面步骤我卸载了驱动:

  1. Unload the old drivers if running:

  • sudo kextunload /Library/Extensions/usbserial.kext

  • sudo kextunload /System/Library/Extensions/usb.kext

Remove the old driver by issuing one of the following commands (depending on your installation):

  • sudo rm -rf /System/Library/Extensions/usb.kext

  • sudo rm -rf /Library/Extensions/usbserial.kext

然后重启PC后,macOS Mojave自带的Apple driver还是无法识别CH34x设备,在/dev下没有cu.wchusbserial1410 设备。请问这个情况如何解决?谢谢!

您好,根据描述可能是usb设备没有成功枚举(未被主机正常识别)。在MacOS10.14上使用ch340/1芯片可以直接使用我司提供官网驱动:/downloads/CH341SER_MAC_ZIP.html 

若驱动安装完毕且重启后无法找到节点,建议在“系统报告”->"硬件"->"USB"页面下,查看是否识别到ch340/ch341对应的usb设备(厂商ID为:0x1A86)。
