A connection, such as a USB connection, between a peripheral device, such as a monitor 10 and a computer 12 can be established following the physical connection of the device to the computer. A device descriptor is supplied to the computer by the device falsely identifying the device as a device of a class known to the computer, such as a generic mass storage device. The peripheral device then transfers a file from memory 14 on the device to the computer, and the file is automatically run to install a device driver for the device on the computer. Once installed the peripheral device can be configured to cease operations using the device descriptor previously supplied and initiate operations using a descriptor for the device which requires the installed driver to be present. Initially supplying a device descriptor of a known class to allow installation in this manner allows the peripheral device to imitate the known device and install the device driver without user interaction in the installation process. |
