Abstract
A caching filter driver which is adapted for communicating with a universal serial bus (USB) mass storage device, the caching filter driver is adapted to: (a) receive a first reading request for a first size data from a USB mass storage driver; (b) determine if requested data which is requested in the first reading request is included in a prefetched read data cache; (c) issue a second reading request for a second size data to the USB mass storage device; and store the second size data in the prefetched read data cache, if the requested data is not included in the prefetched read data cache; and to (d) provide the requested data from the prefetched read data cache; wherein the second size is larger than the first size and the second size data includes the first size data; wherein the caching filter driver resides below the USB mass storage driver.
