Device nodes and right click options

NTDEV

Some devices like HID do not have a “disable device” option on the right-click menu. What properties of the device are used to determine to enable that option or not?

Multiple inputs into this behaviors. PNP_DEVICE_NOT_DISABLEABLE for one. Look up IoInvalidateDeviceState. ACPI can also mark the device as not disable able.
