PROVIDING DEVICE PARAMETERS |
摘要 |
<p>A non-volatile storage device has first and second controllers that provide external access to non-volatile memory using different protocols. In response to a request from the first controller, the second controller retrieves parameters from the non-volatile memory and provides the retrieved parameters to the first controller. In one embodiment, the device parameters are USB descriptors, which may include a vendor ID, a product ID, a product string, and/or a serial number. The first controller may be a Universal Serial Bus (USB) card reader controller. Examples of the second controller include a Secure Digital (SD) controller, a CompactFlash (CF) controller, a MemoryStick controller, or a different type of controller that is able to provide external access to the non-volatile memory. The first controller provides the device parameters to a host during enumeration of the non-volatile storage device. The device parameters may be used to establish settings for the first controller.</p> |
