Abstract
The invention provides a USB device and a data transfer method thereof. The USB device is coupled to a host and transfers at least one packet to the host. The USB device includes a memory, a USB controller, and a transfer management circuit. The memory stores packets. The USB controller is configured to transfer the packets to the host. The transfer management circuit is coupled between the memory and the USB controller and configured to sequentially read the packets from the memory and sequentially transfer the packets to the USB controller, and to perform the following operations: ending the data transfer when a stored content of the memory does not meet a condition for continuing packet transfer; or ending the data transfer when a last transferred packet meets a preset condition and a next packet that follows the last transferred packet does not meet the preset condition.
