 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.
