A method of Universal Serial Bus (USB) data transfer is provided. In one embodiment, a USB device supports a bulk-only transmission mode to transfer data with a USB host, and the USB device comprises a bulk endpoint buffer storing data transferred between the USB device and the USB host through a bulk endpoint of the USB device and an interrupt endpoint buffer storing data transferred between the USB device and the USB host through an interrupt endpoint of the USB device. A first portion of data stipulated to be transferred through the bulk endpoint is stored with the interrupt endpoint buffer. A data path through which data is transferred between the USB host and the USB device is switched to lead to either the bulk endpoint buffer or the interrupt endpoint buffer with a multiplexer.
