Abstract
A method and apparatus for communicating USB data. In one embodiment, the method comprises receiving, by an optimizer executing on a computer and communicatively coupled between a USB storage driver (USBSD) and a USB hub controller driver (UHCD), an SCSI command; transmitting, by the optimizer in response to receiving the SCSI command, the SCSI command to the UHCD; generating, by the optimizer, an SCSI command completion; transmitting, by the optimizer, the SCSI command completion to the USBSD; receiving, by the optimizer, SCSI data associated with the SCSI command completion; transmitting, by the optimizer in response to receiving the SCSI data, the SCSI data to the UHCD; generating, by the optimizer after transmitting the SCSI data, an optimized SCSI status message; transmitting, by the optimizer, the optimized SCSI status message to the UHCD; and transmitting, by the optimizer responsive to an SCSI status completion, the SCSI Status completion to the USBSD.
