Will the environment sensor (temperature, humidity, smoke, water, motion) still work, even if the USB ports are disabled in the BIOS?

The enviroment sensors used and supported by EventSentry require the USB port only to draw power, no communication is sent via USB.

It depends on the mainboard of the server/workstation on whether power is still delivered to the USB ports even when they are disabled. In most cases however, power is delivered to the USB ports, even when you disable the USB ports in the BIOS of the computer.
