On thinkpad x220, USB mouse stopped working in v4.13-rc2. v4.12 was

Now, USB mouse is so common hw that I may have something wrong in my
config...? But I did not change anything there.

Well, your particular USB mouse requires an always-poll quirk, so it's not 
*that* common; therefore ...

In v4.9:

... this is most likely caused by e399396a6b0, and fix for that is queued 
in hid.git as cf601774c9f ("HID: usbhid: fix "always poll" quirk"); I'm 
planning to send it to Linus' tomorrow, but if you can double-check that 
it does fix your issue as well, that'd be appreciated.
