Abstract
An information handling system includes Universal Serial Bus (USB) devices and a baseboard management controller. Each USB device is coupled to a USB interface. The controller gathers an inventory of the USB devices, determines that a first portion of the USB devices are valid USB devices and in response enables the first portion of the USB devices, and determines that a second portion of the USB devices are not valid USB devices and in response disables the second portion of the USB devices.
Claims16
An information handling system, comprising:
- a plurality of universal serial bus (USB) devices, each USB device coupled to a USB interface;
- and
- a baseboard management controller (BMC) configured to gather an inventory of the USB devices, to determine that a first portion of the USB devices are valid USB devices and in response to enable the first portion of the USB devices, and to determine that a second portion of the USB devices are not valid USB devices and in response to disable the second portion of the USB devices,
- wherein in gathering the inventory of the USB devices, the BMC is further configured to retrieve Field Replaceable Unit (FRU) information from the USB devices, and wherein in determining that the first portion of the USB devices are valid, the BMC is further configured to determine that the FRU information for the first portion of the USB devices matches expected FRU information for the USB devices.

A method, comprising:
- providing, on an information handling system, a plurality of Universal Serial Bus (USB) devices, each USB device coupled to a USB interface;
- gathering, by a baseboard management controller (BMC) of the information handling system, an inventory of the USB devices wherein in gathering the inventory of the USB devices, the BMC is further configured to retrieve Field Replaceable Unit (FRU) information from the USB devices;
- determining that a first portion of the USB devices are valid USB devices and in response enabling the first portion of the USB devices, wherein in determining that the first portion of the USB devices are valid, the BMC is further configured to determine that the FRU information for the first portion of the USB devices matches expected FRU information for the USB devices;
- and
- determining that a second portion of the USB devices are not valid USB devices and in response disabling the second portion of the USB devices.
