An example analysis of the use of modules with CH340/CH341 in a virtual machine. In view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Many electronic modules use CH340/CH341 's USB to serial port chips, such as Arduino and NodeMCU.

MacOSX for my host and Ubuntu15.10 on VirtualBox for virtual machines.

It turns out that it can't be used on MacOSX, refer to http://my.oschina.net/u/2306127/blog/614944, and then take care of it.

However, when mounting a USB device in a Ubuntu virtual machine, although it is on the display list, it always reports an error during operation. Later, it didn't work to pre-load the device in the VirtualBox management interface.

Unplug the device, after the virtual machine is rebooted, the device can not be found in MacOSX! Then mount it in the virtual machine, and then OK it.

This method can not quickly switch between host and virtual machine, such as some devices (such as mobile hard disk) can be instantly mounted and unmounted, but after all, it can be used in both systems.

This is the answer to the question about the example analysis of the module with CH340/CH341 in the virtual machine. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
