SYSTEM, APPARATUS, AND METHOD FOR FAST STARTUP OF USB DEVICES |
摘要 |
Exemplary embodiments are directed to fast enumeration of a device in a USB system including a USB device and a USB host. The USB device includes two device descriptors, a memory for holding firmware for operation of the USB device, and a controller for executing the firmware. A first device descriptor is for enumerating the USB device in a firmware-loading mode and a second device descriptor is for enumerating the USB device in an operational mode. The USB host controls a first enumeration of the USB device using the first device descriptor. After the first enumeration, the USB host receives a re-enumerate indicator from the USB device and controls a second enumeration of the USB device using the second device descriptor. |
