Abstract

A portable desktop device and method for host computer system hardware recognition and configuration are provided. The portable desktop device causes on a first boot, the host computer system to recognize hardware devices connected thereto, and to configure hardware configuration files of the portable desktop O/S in accordance with the recognized hardware. Once the hardware configuration files have been configured, the system is rebooted. On the second boot, the host computer determines that the portable desktop has been configured for its hardware, and initiates start-up of the portable desktop.

Claims

1. A portable device having a security specification, the portable device comprising:

I/O hardware for communication with a host system, wherein the host system is connected to a number of hardware devices; and

memory storage comprising;

a storage block with a portable operating system for execution on the host system;

a configuration block for execution on a first boot of the host system, wherein the host system recognizes at least one of the hardware devices and configures at least one hardware configuration file in the memory storage, in accordance with the at least one recognized hardware device; and

a boot process block for execution by the host system, wherein;

on the first boot, the host system sets a previously configured flag indicating that the portable device is other than configured to a value indicating that the portable device has been configured;

the host system reboots to execute the portable operating system on a second boot of the host system, wherein hardware devices which meet the security specification are enabled and hardware devices which fall below the security specification are disabled, based on the at least one hardware configuration file; and

on the second boot of the host system, the host system resets the previously configured flag to the value indicating that the portable device is other than configured.

2. The portable device of claim 1, wherein the portable device is a USB storage device configured for interfacing with the host system via a universal serial bus.

3. The portable device of claim 1, wherein the memory storage comprises a user data block for user data including configuration settings and data files associated with a user of the portable operating system.

4. The portable device of claim 3, wherein multiple instances of the user data block are present in the storage block, one for each of multiple users of the portable operating system.

5. The portable device of claim 3, wherein further storage blocks are present in the memory storage, each having its own portable operating system and user data block for one of multiple users of the portable device.

6. The portable device of claim 1, further comprising authentication hardware and a security process executable on the host system to authenticate a user of the portable device with the authentication hardware.

7. The portable device of claim 1, wherein the hardware devices include a network interface connected to a remote driver repository.

8. The portable device of claim 7, wherein the security specification allows the host system to obtain a device driver for the at least one recognized hardware device from the remote driver repository.

9. The portable device of claim 8, wherein the memory storage comprises a hardware drivers block to which the device driver is added.

10. The portable device of claim 8, wherein the device driver is disabled or restricted in use depending on the security specification.

11. The portable device of claim 1, wherein the memory storage comprises a hardware profiles block defining previous successfully executed configurations associated with the host system, and wherein the configuration block has a same configuration as performed in the previous successfully executed hardware configuration.

12. A method of operating a portable device, the method comprising:

on a first boot of a host computer from the portable device;

recognizing a number of hardware devices connected to the host computer;

configuring a hardware configuration file for a portable operating system stored in memory of the portable device, in accordance with the recognized hardware devices; and

setting a flag indicating that the portable device is other than configured to a value indicating that the portable device has been configured;

rebooting the host computer to execute the portable operating system for operation of a portable computing environment on a second boot from the portable device; and

on the second boot of the host computer from the portable device;

operating a subset of the recognized hardware devices in the portable computing environment, wherein operation of at least one hardware device that meets a security specification of the portable device is enabled and operation of at least one hardware device that falls below the security specification is restricted, based on the hardware configuration file; and

resetting the flag to indicate that the portable device is other than configured.

13. The method of claim 12, further comprising interfacing the portable device with the host computer via a universal serial bus.

14. The method of claim 12, further comprising:

determining whether a network interface card is present within the hardware devices; and

determining whether the any network interface card present is connected to a remote driver repository.

15. The method of claim 14, further comprising the security specification allowing the host system to obtain a device driver for the at least one hardware device from the remote driver repository.

16. The method of claim 14, further comprising adding the device driver to a hardware drivers block of the portable operating system.

17. The method of claim 12, further comprising retrieving configuration information for the hardware devices during a first session, wherein the portable device does not support operation of the portable computing environment a first time the portable desktop device is used with the host computer.

18. The method of claim 17, further comprising updating the hardware configuration file with modifications identified from the configuration information, wherein the portable device supports operation of the portable computing environment during a subsequent session.

19. The method of claim 12, further comprising saving a hardware profile defining a previous successfully executed hardware configuration and associating the hardware profile with a system identification of the host computer.

20. The method of claim 19, further comprising the host computer performing a same hardware configuration as was performed in association with the previous successfully executed hardware configuration.
