Just bought thinkpad t480 and have some problems with my usb devices: with my mouse and keyboard. Mouse and keyboard just don’t work for 1 sec randomly. Fresh installed arch linux.

try

Intel chipset driver. That was always the chipset driver.Have you tried on any other OSes besides this install? Did they work during the initial install process and just later on stopped working?
Also USB A or USB C?
usb A. looks like on arch installation - without problems
@someoneFromInternet what BIOS version do you have? You can update firmware on T480 without USB stick. Use
fwupdutil.version: N24ET49W (1.24)
@someoneFromInternet looks old. Current BIOS version is 1.52.
You may have bugged version of thunderbolt controller as well.
Run
fwupdmgr get-devicesas root to check Thunderbolt Firmware version. Find “T480 Thunderbolt Controller” in output and check “Version” parameter.It should say “20.00” or higher. If it’s lower then I highly recommend you to upgrade your firmware ASAP!
Install fwupd and run these commands to update your firmware (run as root):
fwupdmgr refresh fwupdmgr updateFor more info check out this wiki page:
https://wiki.archlinux.org/title/Fwupd@someoneFromInternet let me know if the issue will resolve after an update.
No, I think issue not resolved after update thunderbolt, but I just reinstalled arch and now all works good
