https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=294303 Bug ID: 294303 Summary: devd(8) overwrites "bus" variable for "nomatch" event Product: Base System Version: 15.0-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: phk@FreeBSD.org When my Canon Lide printer is attach, no driver matches and devd(8) goes quantity surveying to find something. When doing that it sets two different values for "bus": setting timestamp=1775570495.177197 setting vm_guest=none setting bus=0 setting hubaddr=1 setting port=2 setting devaddr=2 setting interface=2 setting ugen=ugen0.2 setting vendor=0x04a9 setting product=0x1912 setting devclass=0x00 setting devsubclass=0x00 setting devproto=0x00 setting sernum=4F3AFB setting release=0x0100 setting mode=host setting intclass=0xff setting intsubclass=0xff setting intprotocol=0xff setting bus=uhub0 I'm catching that with: nomatch 1000 { match "vendor" "0x04a9"; match "product" "0x1912"; match "sernum" "4F3AFB"; action "echo FOO!; chmod 666 /dev/usb/0.$devaddr.0"; }; But have to hard code the USB bus name because "uhub0" is not what I need. See also: #198015 which seems to be the same problem presumably fixed 10 years ago? Feel free to stick this example in the handbook's section 7.7.3.2: 7.7.3.2.
