Abstract

USB-based peripheral device for operation with a host system, having a driver for operation with the host system, wherein the driver is stored in a memory in the USB-based peripheral device, and with startup of the peripheral device on the host system, prompting automatic installation of the driver on the host system.

Claims

1. A USB-based peripheral device for operation with a host system, having a driver for operation with the host system, wherein the driver is stored in a memory in the USB-based peripheral device, and with startup of the peripheral device on the host system, prompting automatic installation of the driver on the host system.

2. The USB-based peripheral device as claimed in claim 1, wherein the USB-based peripheral device is an external or internal peripheral device.

3. The USB-based peripheral device as claimed in claim 1, wherein the USB-based peripheral device is a peripheral device with a driver of unknown device class which is necessary for operation.

4. The USB-based peripheral device as claimed in claim 3, wherein the memory in the peripheral device stores an attribute which is associated with a mass-storage device class and which can be output to the host system using a descriptor.

5. A method for starting up a USB-based peripheral device on a host system, comprising the steps of:

the peripheral device outputting a descriptor for a device class defining mass storage when said peripheral device is first connected to a USB interface in the host system;

the host system taking a driver which is available for the mass-storage device class as a basis for integrating the peripheral device as a mass-storage drive for system access operations;

automatically installing a driver stored on the peripheral device on a hard disk associated with the host system; and

entering the driver in the registry file in the host system.

6. The method as claimed in claim 5, further comprising the steps of:

the peripheral device automatically signing off from the host system following driver installation and entry into the registry file; and

the host system removing the integration of the peripheral device as a mass-storage drive.

7. The method as claimed in claim 6, further comprising the steps of the peripheral device signing onto the USB interface again and outputting to the host system a descriptor of unknown device class which is associated with the installed driver.

8. The method as claimed in claim 7, further comprising the steps of the host system automatically assigning the driver required for operating the peripheral device on the basis of the entry in the registry and loading the driver for the purpose of executing a target application.
