Hi, when i connect screen from usb type A -> type-c cable everything is fine, but if i use type-c-> type-c cable screen doesn't turn on and COM-port doesn't exist. I catch this problem on maibenben x558 and lenovo thinkpap t14. What i doing wrong?

That USB-C cable is known to be power+data? Does it have 6 pins or 24?

I connected my phone for the test and it was detected and I was able to copy photos from it to a folder on my laptop, but the com device was not detected.

As @c0ldJS said, I would advise to try another USB-C/USB-C cable. To test the cable you can try to connect your phone to your computer with it first, and see if your phone detects that a computer is plugged to confirm the cable can handle data
