the touchpad isn't detected in lspci, neither in lsusb, only xinput list

i have figured out that this is all (probably) caused by elan-i2c-ids.h in the elan_i2c driver and my laptop's ELAN id is probably not in it, is there any way for me to get my id?
edit:
i found that with
# sudo acpidump | grep -C3 -i elanmy id is ELAN901C

Have a look at https://bugzilla.kernel.org/show_bug.cgi?id=207759 which is marked fixed

i've seen that this issue is no where near mine, but it seems its merged into 5.13-rc1, which i was in rc4, and this issue still exists
adding my id (901C) really didnt fix anything, as i probably got the id the wrong way
using windows my id was 0000

Why do you think the device ID is not recognized? If it was not recognized what is causing the elan_i2 module to be loaded? What device did the elan_i2 module detect and is processing reports for?

This is a problem I had with my laptop that also has an ELAN touchpad, I fixed it by blacklisting the elan-i2c kernel module, I added the following to /etc/modprobe.d/blacklist.conf:
blacklist elan_i2cThen, I rebooted and the touchpad worked.
I don't know why it happens in the first place though.
