Abstract

An intermediate device, including: (a) a wired USB communications component; (b) a wireless USB communications component; (c) a memory unit; (d) a processor, connected to the wired USB communications component, to the wireless USB communications component and to the memory unit, and (e) a USB class compliant driver emulator constructed in response to at least one characteristic of the USB device.

Claims

1. A method for connecting a universal serial bus (USB) host and a USB device, the method comprises:

initiating a first USB connection between an intermediate device and the USB device, in response to a USB class of the USB device, by using at least one USB class compliant driver emulator that is included in the intermediate device, wherein the USB class defines a USB protocol selected from multiple wireless USB protocols and multiple wired USB protocols;

setting up a second USB connection between the intermediate device and the wireless host, wherein the second USB connection is selected between a wireless connection and a wired connection;

processing input data received from a source device to provide output data; and

sending the output data to a target device;

wherein the target device and the source device are selected from the USB host and the USB device and wherein the sending is using the selected USB protocol.

2. The method according to claim 1, wherein the initiating of the first USB connection is an initiating of a wired connection between the intermediate device and the USB host, so as to provide wireless USB host capabilities to the USB host, and wherein the setting up of the second USB connection is a setting up of a wireless connection between the intermediate device and the USB device.

3. The method according to claim 1, wherein the initiating of the first USB connection is an initiating of a wired connection between the intermediate device and the USB device, so as to provide wireless USB host capabilities to the USB device, and wherein the setting up of the second USB connection is a setting up of a wireless connection between the intermediate device and the USB host.

4. The method according to claim 1, whereas the setting up is responsive to at least one first parameter defined during or prior to the initiating;

and wherein the initiating is carried out in response to at least one second parameter defined during or prior to the setting up.

5. The method according to claim 1, wherein the processing comprises separating the payload from one or more first protocol overhead bits.

6. The method according to claim 5, wherein the processing includes adding one or more second protocol overhead bits to the payload.

7. The method according to claim 1 further comprises determining the USB class of the USB device in response to a descriptor of the USB device.

8. The method according to claim 1 further comprises determining the USB class of the USB device in response to information which is included in the input data received from the USB device.

9. The method according to claim 5, wherein sending comprises creating and transmitting of at least one control massage, wherein the creating and transmitting are conveniently carried out in response to the first protocol overhead bits.

10. The method according to claim 1, wherein sending includes creating and transmitting at least one control massage.

11. The method according to claim 1, further comprising determining whether the USB device belongs to a USB class which is supported by the USB class compliant driver emulator.

12. The method according to claim 1, further comprising providing power to the USB device.

13. The method according to claim 1, wherein the initiating comprises initiating the wired connection between the intermediate device and multiple wired USB devices of different USB classes.

14. An intermediate device, comprising:

a wired universal serial bus (USB) communications component;

a wireless USB communications component;

a memory unit;

a USB class compliant driver emulator constructed in response to at least one characteristic of a USB device; and

a processor, coupled to the wired USB communications component, to the wireless USB communications component, to the USB class compliant driver emulator and to the memory unit;

wherein the processor is adapted to initiate a first USB connection between the intermediate device and the USB device, in response to a USB class of the USB device, by using the USB class compliant driver emulator and wherein the USB class defines a USB protocol selected from multiple wireless USB protocols and multiple wired USB protocols.

15. The intermediate device to claim 14, wherein the wired USB communication component is adapted to initiate a wired connection with a USB host, so as to provide wireless USB host capabilities to the USB host, and wherein the wireless USB communication component is adapted to set up a wireless USB connection with a wireless USB device.

16. The intermediate device to claim 14, wherein the wired USB communication component is adapted to initiate a wired connection with the USB device, so as to provide wireless capabilities to the USB device, and wherein the wireless USB communication component is adapted to set up a wireless USB connection with a wireless USB host.

17. The intermediate device according to claim 14, wherein the wireless USB communication component conveniently is adapted to set up a wireless USB connection with the host in response to at least one first parameter defined during or prior to the initiation of a wired USB communication with a USB device;

and the wired USB communication component conveniently is adapted to initiate a wired connection with the USB device in response to at least one second parameter defined during or prior to the setting up of a wireless USB connection with a host.

18. The intermediate device according to claim 14, whereas the processor is adapted to separate a payload from a first protocol overhead bits.

19. The intermediate device according to claim 14, wherein the processor is adapted to add second protocol overhead bits to the payload.

20. The intermediate device according to claim 14, wherein the processor is further adapted to determine the USB class of the USB device in response to a descriptor of the USB device.

21. The intermediate device according to claim 14, wherein the processor is adapted to determine the USB class of the USB device in response to information which is included in an input data received from the USB device.

22. The intermediate device according to claim 17, wherein the processor, the wired USB communication component and the wireless USB communication component are adapted to create and to transmit at least one control massage in response to information consisted in the first protocol overhead bits.

23. The intermediate device according to claim 14, wherein both the processor, the wired USB communication component and the wireless USB communication component are adapted to create and to transmit at least one control massage.

24. The intermediate device according to claim 14, further adapted to determine whether the USB device belongs to a USB class which is supported by the USB class compliant driver emulator.

25. The intermediate device according to claim 14, further adapted to provide power to the USB device.

26. The intermediate device according to claim 14, wherein the intermediate device is adapted to set the wired USB communication with multiple wired USB devices of different USB classes.
