Description:
ch341-uart converter not working with kernel version 5.13.10-arch1-1

Additional info:
Downgrading kernel to 5.13.8-arch1-1 solve the problem

Steps to reproduce:

Can you test 5.13.9-arch1-1 and see if that works. If it does then I would suggest testing with [1] reverted, which was added in 5.13.10.

With 5.13.9-arch1-1 It works fine

I do not understand how to test with [1] reverted.
Best Regards

Step by step:

pacman -S asp base-devel # install required packages
asp checkout linux # fetch the PKGBUILD
cd linux/trunk
Edit PKGBUILD in your preferred text editor, on line 42 add:
git revert -n 9fc923d27852aebbd8af0ac988dc66bfb4aa7d5d

gpg --auto-key-locate nodefault,wkd --locate-keys heftig@archlinux.org # fetch and add the key used to sign 5.13.10-arch1-1 to your users keyring [1]
At this point I suggest enabling parallel compilation see [2] to reduce build time
makepkg -rsi # build and install the kernel with that commit reverted, build can take a long time.

Please try linux-mainline 5.14-rc6 [1] to see if the issue has already been fixed upstream. I doubt it has been but it needs to be checked.
Then either reply to [2], link includes instructions on how to reply.
Or open a bug report on [3] Component USB Product Driver referencing the commit 9fc923d27852aebbd8af0ac988dc66bfb4aa7d5d and subscribe Johan Hovold <johan@kernel.org> to the bug report.
See [4] for more information on what information to include.

Try now with kernel 5.14.2, as it has the commit reverted that loqs wrote about.

I just run into the same issue, appears to be unresolved with 5.14.14-arch1-1

Dmesg shows no error, but no communication possible.

See also https://github.com/espressif/esptool/issues/683 for all details and another user reporting of this issue.

Should be fixed in upstream since 5.14? https://bugzilla.kernel.org/show_bug.cgi?id=214131

EDIT: Issue solved! Appears to be an hardware issue with the NodeMCU ESP8266. Solution for all my 3 ESP8266 is https://github.com/espressif/esptool/issues/441#issuecomment-728335810
Thus, I can also report that kernel 5.14.14-arch1-1 is working fine with CH340
