Summary:A technique includes holding a bus interface of a removable device that is inserted into a connector of a computer system in a state to prevent the device from communicating with a communication link. The communication link is coupled to the connector and is associated with operating system access to the device. The method includes a baseboard management controller communicating with the device using a channel other than the communication link while the bus interface of the device is held in the state; the baseboard management controller performing a security operation corresponding to the device based on the communication with the device using the channel; and the baseboard management controller releasing the bus interface of the device from the state to allow the device to communicate with the communication link in response to the baseboard management controller completing the security operation.
