https://bugzilla.tianocore.org/show_bug.cgi?id=766 Update logic to not return an error from UsbBootRequestSense() if a Request Sense command responds with no sense information. It is legal for a USB mass storage device to respond to a Request Sense command with a SenseKey of USB_BOOT_SENSE_NO_SENSE and an Additional Sense Code of USB_BOOT_ASC_NO_ADDITIONAL_SENSE_INFORMATION. This is described in Section 3.3 of the Universal Serial Bus Mass Storage Specification For Bootability: http://www.usb.org/developers/docs/devclass_docs/usb_msc_boot_1.0.pdf The previous logic returned an error of EFI_NO_RESPONSE and this caused USB mass storage devices such as a USB floppy drive to not be detected.
