ABSTRACT:
A data transfer apparatus improving data transfer rate regardless of the original transfer mode in a USB interface is disclosed. A computer includes a bulk packet generation unit and an isochronous packet transmission unit. The bulk packet generation unit generates a bulk packet (or a control packet) which is a USB packet and has a predetermined structure including a first data area by describing data which is taken as an object of transfer in the first data area. The isochronous packet transmission unit generates an isochronous packet which is a packet in USB isochronous transfer and has a predetermined structure including a second data area by incorporating at least one bulk packet into the second data area, and isochronously transfers the isochronous packet to the mobile telephone over the USB interface.
