Used to specify which USB devices are allowed or denied. Each rule is case-insensitive and of the form {Allow: | Deny:} followed by any number of <tag>=<value> qualifiers. Multiple rules should be separated by semicolons. Comments start at '#' and continue until a semicolon. For example 'Allow: VID=1234 PID=5678 # Comment ; Deny: Class=03'. Supported tags are VID, PID, REL, CLASS, SUBCLASS, PROT.
