Abstract
An apparatus and method for write posting in a universal serial bus (USB) system includes a host computer connected to USB devices via a USB. The host computer generates requests to write data to memory within the USB device. The host computer includes a queue for posting the write requests on generation thereof. The write requests are posted in the queue until the host computer transmits a single data packet generated from the posted write requests. The Data packet is generated in response to the host computer generating a request to read data from the USB device, the host computer determining that the most recently posted write request is directed to a memory location within the USB device which is nonpostable, or an indication that the queue lacks storage space for subsequent write requests. The USB device receives the transmitted Data packet from the host computer and writes data to internal memory locations in accordance with the received Data packet.
