CH382L, M.2 to PCIe adapter on SBC not recognised by Linuxcnc

Hi,
I have installed Linuxcnc 2.9.2 on a 64-bit x86 SBC (LattePanda Delta) and I am trying to access LPT with a WCH382L chip through PCIe. PCIe socket of the card is connected to M.2 socket of SBC using an adapter. After powering the addon card with the necessary 12V, I am able to read 3.2V or 0v from random pins but there is no sign of detection of the parallel port on the system. Commands like lspci and dmesg doesn't return any information about a parallel port. Please correct me if I am wrong but as I understood while reading forum posts a supported chip should be recognized by the system automatically. I have seen some posts about people were able to use an addon card with CH382L, but information about M.2 to PCIe adapters for Linuxcnc is limited. I did some tests reading values from pins while running the parallel port tester program with various recommended hex addresses but it wasn't successful. By the way, I am able to use this addon card connected to PCIe slot of a motherboard that is running Windows 7 successfully.
So what could the issue be? Is it the notorious CH382L, M.2 to PCIe adapter, or am I supposed to do something for the system to recognize the card? Your help is greatly appreciated.
Thanks.

First you have to make sure your M.2 slot is actually PCI-E as the same slot can also be SATA and this will not work.
Some PC's have the option to choose what the slot does in BIOS, some do that automatically, and some do nothing at all as they have only one of the options.
Another thing to change in BIOS is to lower the PCI-E speed/generation to the lowest possible, as those adapter cables are pretty bad so most will not do gen3 or gen4 at all.

Thanks for your suggestions. I checked M.2 port again and it is a PCIe slot. PCIe speed setting on BIOS was on auto, other options were Gen1 and Gen2. I chose Gen1 and checked with lspci -v again and still no sign of a serial, parallel port or chip name.

Let's have a look at your $lspci and $lsmod

Thanks for your suggestions. lsmod outputs "parport 73728 3 parport_pc, lp, ppdev" in one of its lines if that was you were suggesting me to check.
As far as I read from the forum addon card should be detected automatically but there is no sign of detection, so I am not sure how the kernel is supposed to drive it. I tried "make Makefile" on driver from manufacturer but it outputs errors and I have seen a few people mentioned the same errors on this forum. But unlike my situation their card appeared on lspci -v and they fixed the problem with some workarounds. Please correct me if I'm wrong in any of these.
I tried loadrt hal_parport cfg="0 out". 0xe000, 0xe100, 0xe010 too.

See edit two up (addy 0x3050)
$ cat /proc/ioports | grep parport
Should output 0000-0000 : parport0 if present. Output nothing if not.

0x3050 also didn't work. Says "No parport registered at 0x3050." and no change at pin voltages when I toggle pins on test software.
$ cat /proc/ioports | grep parport outputs nothing.

Also, there are two M.2 PCIe slots on the SBC and I disabled the one I am not using (E-keyed) from BIOS so there is no confusion. Result wasn't different than before disabling though. Here are also lspci -v only PCIe part:

Interesting (not really). See if it does anything more interesting if you throw in the driver. Not sure what 'few people mentioned the same errors on this forum' meant, but they lied to you. WCH's stuff always works....
$ sudo apt update
$ sudo apt install linux-headers-$(uname -r) build-essential git
$ git clone https://github.com/WCHSoftGroup/ch35_38x_linux.git
$ cd ch35_38x_linux/driver_main/
$ make
$ make install
$ sudo shutdown now

I encountered multiple issues while installing.
I was getting "Raspi-firmware: missing /boot/firmware, did you forget to mount it? error" then as suggested by someone "sudo dpkg --purge raspi-firmware" apparently fixed it.
Then while "make" stage I was getting "Skipping BTF generation xxx. due to unavailability of vmlinux" then as suggested by someone;
apt install dwarves
cp /sys/kernel/btf/vmlinux /usr/lib/modules/`uname -r`/build/
seemed to fix that issue, but now this issue is happening during "make" stage:
make -C /lib/modules/6.1.0-16-rt-amd64/build M=/home/ardacaner/drvyuk/ch35_38x_linux/driver_main modules

As I read threads about this btfids issue, the solution to that doesn't seem straightforward. I will keep looking into this later as it is getting very late here. Suggestions are appreciated as always. Thank you.
