Abstract
A bulk transfer control method of a universal serial bus (USB) device includes a timer for counting transmission time of a buck transfer. When the transmission time counted reaches a transmission time setting value, a trigger signal is issued to a transfer end event generator. Then, the transfer end event generator issues a transfer end event signal to a data processing unit so as to end the bulk transfer. Moreover, a USB device and its bulk transfer control circuit are also provided.
