Abstract: Certain aspects relate to monitoring and managing storage drives installed on a backplane and performing backplane controller firmware update through a universal serial bus (USB) interface. When the backplane controller is connected to a host computer via the USB interface, the backplane controller sends USB descriptors to the host computer through the USB interface such that the host computer recognizes the backplane controller as a specific human interface device (HID) device based on the USB descriptors. Thus, the backplane controller and the host computer may transmit backplane drive management messages, such as the result to monitor and manage the storage drives, or the control commands and control data to monitor and manage the storage drives and to update the firmware of the backplane controller, as USB HID reports in a predefined format based on the USB descriptors.

Abstract: Present disclosure relates to backplane controller configured as human interface device (HID) device to communicate with host computer through USB interface. Backplane controller includes: processor, memory, HID universal serial bus (USB) interface, and non-volatile memory. Non-volatile memory stores certain USB descriptors, drive management module, USB HID device driver, and firmware of the backplane controller. Firmware performs one or more of following operations: (a) connecting to host computer through USB interface, (b) sending USB descriptors to host computer to act as specific HID device, (c) instructing USB HID device driver of backplane controller to generate first USB HID report, (d) sending USB HID report to host computer through USB interface, (e) receiving second USB HID report from host computer through USB interface, (f) instructing USB HID device driver to retrieve and process report data from second USB HID report. USB interface includes HID USB interface, USB interface bus, host USB interface.
