I added a debugging printf to devctl_queue_data() to figure out why devd doesn't react when I plug in a USB keyboard (turns out it's reported as ukbd0 instead of kbd1, but that's a diffrent issue). I was quite interested to discover just how much junk passes through devctl: # dmesg | grep devctl devctl_queue_data(): +npx0 at on nexus0 devctl_queue_data(): +acpi_timer0 at on acpi0 devctl_queue_data(): +acpi_cpu0 at on acpi0 devctl_queue_data(): +acpi_tz0 at on acpi0 devctl_queue_data(): +acpi_acad0 at on acpi0 devctl_queue_data(): +acpi_cmbat0 at on acpi0 devctl_queue_data(): +acpi_cmbat1 at on acpi0 devctl_queue_data(): +acpi_lid0 at on acpi0 devctl_queue_data(): +acpi_button0 at on acpi0 devctl_queue_data(): +acpi_button1 at on acpi0 devctl_queue_data(): ?
