CH341 USB to Serial Read & Write Error!

[ken 0]

Use Tinker Board 2 Debian 10 V2.0.4 

CH341 USB to Serial Recognition works well.

However, there is no actual communication.

But CH341 USB to Serial Module connect Raspberrypi4, communication works well.

I don't know why, because it is recognized, but data cannot be transmitted.

Maybe I downloaded the kernel header and built a new CH341 Driver, but an error occurs.

Hi Ken,

You can use this patch file to update ch341.c to the newest version. 

This patch will be included in the next OS image release.

Hello,

I am having this problem with tinker board s Debian 10, but i do not have the skills to make a kernel fresh install. Can you, please, tell me how to do it? Or Maybe TzuWen_Chang can tell me how to patch ch341 driver.
