https://bugzilla.tianocore.org/show_bug.cgi?id=782 Update the Request Sense check for the Request Sense Key of USB_BOOT_SENSE_UNIT_ATTENTION. For this Sense Key, the Additional Sense Key to EFI_STATUS mappings are: USB_BOOT_ASC_MEDIA_CHANGE -> EFI_MEDIA_CHANGE USB_BOOT_ASC_NOT_READY -> EFI_NOT_READY USB_BOOT_ASC_NO_MEDIA -> EFI_NOT_READY All others -> EFI_DEVICE_ERROR A USB flash drive is returning Request Sense Key of USB_BOOT_SENSE_UNIT_ATTENTION and an Additional Sense Key of USB_BOOT_ASC_NO_MEDIA for a few seconds before returning an Additional Sense Key of USB_BOOT_ASC_MEDIA_CHANGE. The current logic treats this initial Request Sense info as an error and reties the command 5 times before failing completely. With this change the USB Flash Drive works correctly.
