With kernel timestamps (under -current) I see the same sequence, over
and over.  The timing is at _very_ consistent intervals, with the
reconnect happening at ~2.2 seconds after the disconnect, and the
disconnect happens almost exactly 60 seconds later.

This has been happening to me for at least a year or more, and was
reported several times (although no PR files).  I know that others
have also seen this.

Note that this does NOT happen while the Xserver has ownership of the
console.  Some suspicion is that the Xserver does something(tm) that
performs some sort of keep-alive on the mouse's USB connection, and
that without the Xserver doing the keep-alive the connection times
out.  But no real investigation was done, as far as I know.

(Thanks for filing the PR - perhaps we can get some traction!)

Yes, that would be a separate issue.  Please file a new PR.
