Hi! First of all sorry for late response. Check out updated README that contains "Tutorial on Ubuntu" (Thanks @ensismoebius ). If this does not help, we will think about it some more, ok?

[ensismoebius]

Ok, thank you too and congrats for the job!

Hello,
I have the same problem on Ubuntu 20.4 (x86_64) kernel 5.15.0-56...
SecureBoot is not active and brltty is not installed.
Tell me if you need information about my configuration.

As I remember there are mismatches between Arch and Ubuntu and there were already conflicts with it (one solution worked for Arch, but did not work for Ubuntu and vice versa), so I created a separate "ubuntu" branch. Try typing this:

git clone -b ubuntu https://github.com/juliagoda/CH341SER.git

and do the rest according to the tutorial and let me know what came out

[ensismoebius]

@EddyMercier can you post the compiler log?

[EddyMercier]

Hello,

I have the same error message with the ubuntu branch !
I don't understand the message because 'ch34x_write_room' is well declared as unsigned (but I am a professional in C++...)
Meaby the problem is that the var "room" is not a 'unsigned int' but a 'int' (but I am a professional in C++...)

Thanks for your job !

[juliagoda]

could you put here the results anyway? C language differs often when it comes to types behaviour. Are you sure 100% you are using the branch? I don't have Ubuntu, so I have to rely on someone else's results

[juliagoda]

No need to put anything, I'll try it on workflow with ubuntu

[juliagoda]

Ok. Try again

[yamelsenih]

Thanks @juliagoda let me test it in Ubuntu branch

hi, I try with the ubuntu branch, but this happend.

Hi, this is because you have secure boot.

[yamelsenih]

I tasted it for Ubuntu and all right but never is loaded the driver when I connect the device. All test was over Ubuntu branch

Also I tasted for Raspbian with main branch and all also is ok but the driver never is loaded for device

[juliagoda]

Is there any log/message about this that can be copied here? If not, maybe a screenshot using scrot -d? Additionally, is there at least one person for whom this driver under Linux Mint/Ubuntu works? If so, please provide some kind of response.

[juliagoda]

after trying to upload driver, attach the file here, which has the content of the result :

sudo dmesg

[jd-apprentice]

Have anyone solved this? I'm on Ubuntu 22.04 lts, kernel 5.15.0-58-generic EDIT: Yes i'm using ubuntu branch

[mattm-boop]

I have the same error using the ubuntu branch on ubuntu 20.04, kernel 5.15.0-58-generic. The output looks exactly the same as linker3000 reported above.

[jd-apprentice]

For anyone trying to use a chinese arduino (CH340g) I made it work downloading the installer of the 1.8 then using the 2.0+ I wrote a simple guide about it ->

[JacobKan]

I am using Ubuntu 18.04, and meet the same issue.
However, I make it successfully after I change to main branch.....
