Abstract
A computer system and a method for controlling a USB FDD include a disk driver process routine including steps of requesting a disk drive process from a host program, if a subject of the disk drive process is a USB FDD and it is also necessary to communicate through the USB HC, and generating an I/O trap system management interrupt (SMI). After generating the SMI, the communication to the USB FDD through the USB HC is executed by a split process. After finishing the split process, a status indicating a status of result of the split process is outputted to the host program.
