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
usbcore.autosuspend=-1kernel switch.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
