Abstract

Methods, peripheral devices, and computer program products are provided for loading I/O device drivers from a peripheral device to a data processing system. First device identification information is communicated from the peripheral device to the data processing system. The first device identification information corresponds to a first I/O device driver in the data processing system. A second I/O device driver is communicated from the peripheral device to the data processing system using the first I/O device driver in the data processing system. Second device identification information is communicated from the peripheral device to the data processing system. The second device identification information corresponds to the second I/O device driver.

communicating a second I/O device driver from the peripheral device to the data processing system using the first I/O device driver in the data processing system; and

communicating second device identification information, which is different from the first device identification information, from the peripheral device to the data processing system that identifies the peripheral device as corresponding to the second I/O device driver.

2. The method of claim 1, further comprising carrying out further communications between the peripheral device and the data processing system using the second I/O device driver.

3. The method of claim 1, wherein the first I/O device driver in the data processing system comprises a predefined USB class driver, and wherein:

the communicated first device identification information identifies the peripheral device as corresponding to the predefined USB class driver in the data processing system;

communicating the second I/O device driver comprises communicating a custom USB driver to the data processing system using the predefined USB class driver; and

the communicated second device identification information, which is different from the first device identification information, identifies the peripheral device as corresponding to the custom USB driver in the data processing system.

4. The method of claim 3, wherein:

the predefined USB class driver comprises a USB storage class driver; and

the first device identification information identifies the peripheral device as a storage device that corresponds to the USB storage class driver; and

the custom USB driver is communicated to the data processing system using the USB storage class driver.

5. The method of claim 3, wherein communicating the custom USB driver to the data processing system comprises installing the custom USB driver into a memory of the data processing system.

6. The method of claim 3, wherein communicating the custom USB driver to the data processing system comprises:

loading an executable file from the peripheral device into the data processing system; and

running the executable file to install the custom USB driver into a memory of the data processing system.

7. The method of claim 3, wherein communicating the custom USB driver to the data processing system comprises:

displaying to a user an executable file that is on the peripheral device; and

causing the executable file to be executed by the data processing system based on one or more selections by a user, wherein the executable file installs the custom USB driver in the data processing system.

8. The method of claim 3, wherein:

the predefined USB class driver comprises a USB storage class driver;

the first device identification information identifies the peripheral device as a storage device that corresponds to the USB storage class driver; and

communicating the custom USB driver to the data processing system comprises;

displaying to a user an executable file that is on the peripheral device in a window formed by an operating system within the data processing system; and

causing the executable file to be executed by the data processing system based on a selection by a user, wherein the executable file installs the custom USB driver in the data processing system.

9. The method of claim 1, wherein the peripheral device communicates the first device identification information to the data processing system based on a determination that the data processing system does not have an I/O device driver that corresponds to the second device identification information.

10. The method of claim 1, further comprising:

communicating the second device identification information from the peripheral device to the data processing system; and

determining whether the data processing system has an I/O device driver that corresponds to the second device identification information, wherein the first device identification information is communicated to the data processing system based on the determination.

11. A peripheral device comprising:

an I/O interface that is configured to communicate information to a data processing system; and
