 Issues like these can in part be mitigated with host-based filtering, such as explicit whitelisting of physical USB

 A possible secure solution for this problem would be to completely separate security-critical USB devices such as
 keyboard and mouse from everything else. A practical implementation of this would require two separate USB host
