Abstract:
1. A method to control a device connected to a computer and having at least one re-configurable configuration parameter defining an operating characteristic of the device, a storage medium controlled by a first microcontroller, and a second microcontroller, wherein the re-configurable parameter controls an as aspect related to the storage medium, comprising: operating the device to identify itself to the computer as a first device capable of communicating using a first protocol associated with the storage medium and as a second device capable of communicating using a second protocol associated with the second microcontroller; in response to receiving a message from the device identifying itself to the computer as a first device capable of communicating using a first protocol associated with the storage medium, operating the computer to associate a first unique peripheral device identifier with the microcontroller connected to a storage medium whereby the computer uses the unique peripheral device identifier to address the storage medium of the device; in response to receiving a message from the device identifying itself to the computer as a second device capable of communicating using the second protocol associated with the second microcontroller, operating the computer to associate a second peripheral device identifier with the second microcontroller wherein the at least one re-configurable parameter is controlled via the second microcontroller; controlling updates to the value of the at least one re-configurable parameter with the second microcontroller; storing the value of the at least one re-configurable parameter in non-volatile memory on the second microcontroller; and upon start-up of the device, transmitting the value of the at least one re-configurable parameter from the second microcontroller to the first microcontroller.
