My ASI2600 data sheet insists that it must have USB and power connected but it certainly works without the power being connected.
Power is needed for cooling of course but apparently not otherwise. I do use it at times without cooling and have found no unexpected problems.
Correction: The ZWO does require power. my Eagle was switching power on automatically but not cooling.
