   * USB devices are by-default put into ''/dev/uhid#'' paths with older [[https://man.freebsd.org/cgi/man.cgi?query=uhid&sektion=4&apropos=0&manpath=FreeBSD+14.1-RELEASE+and+Ports|uhid]] and [[https://man.freebsd.org/cgi/man.cgi?query=usb&sektion=4&apropos=0&manpath=FreeBSD+14.1-RELEASE+and+Ports|usb]] drivers ((using these older drivers prevents USB multimedia keys from working and presumably would require ''uhidd'' to solve; hence use the newer ''usbhid'' driver with ''hw.usb.usbhid.enable="1"'' and ''uhidd'' as-needed on game controllers))
