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.

@someoneFromInternet what BIOS version do you have? You can update firmware on T480 without USB stick. Use fwupd util.

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-devices as 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 update

@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
