ABSTRACT:
A method and apparatus for improving the performance of Universal Serial Bus mass storage devices is provided wherein a local extender located adjacent to a host computer is used in combination with a remote extender located adjacent to a peripheral device. The local extender and remote extender units jointly implement a protocol that enables bulk data to be transferred efficiently between the units even when the transmission delay between the units exceeds 1 microsecond. No alterations to the host computer or the USB mass storage device are required to achieve the improved performance. An improved method for connecting USB mass storage devices to a host controller is provided.
