Method and system for hardware based implementation of USB 1.1 over a high speed link
View Patent ↗Certain aspects of a method and system for a hardware-based implementation of USB 1.1 over a high-speed link may comprise translating at a client side of a client server communication system, USB protocol messages comprising a first USB standard to corresponding encapsulated USB protocol messages, wherein the USB protocol messages comprising the first USB standard are received from a client device at the client side of the client server communication system. The translated corresponding encapsulated USB protocol messages may be communicated from the client side to a server at a server side of the client server communication system.
1. A method for communicating packets, the method comprising:
in a client-server communication system:
communicating, from a server side hub transaction translator, a first acknowledgement packet to a server in response to receiving a start setup packet from said server;
communicating an encapsulated setup packet to at least one USB device based on said communicated first acknowledgement packet; and
communicating, to said server, a second acknowledgement packet that is received from said at least one USB device in response to receiving one or more complete setup packets from said server.
2. The method according to claim 1 , wherein said client-server communication system is capable of handling USB 1.1 protocol packets.
3. The method according to claim 1 , comprising communicating said encapsulated setup packet to said at least one USB device at a client side of said client server communication system via a client side hub transaction translator.
4. The method according to claim 1 , wherein said client-server communication system is capable of handling USB 2.0 protocol packets.
5. The method according to claim 1 , comprising receiving one or more complete setup packets from said server based on said communicated first acknowledgement packet.
6. The method according to claim 1 , comprising communicating not yet acknowledgement packet to said server, if said server side hub transaction translator has not received said second acknowledgement packet from said at least one USB device.
7. The method according to claim 1 , wherein said at least one USB device comprises a USB interface that is USB 1.1 protocol compliant.
8. The method according to claim 1 , wherein said server comprises a USB interface that is USB 2.0 protocol compliant.
9. The method according to claim 1 , comprising communicating said encapsulated setup packet to said at least one USB device via an Ethernet link.
10. The method according to claim 1 , comprising receiving said second acknowledgement packet from said at least one USB device via an Ethernet link.
11. A system for communicating packets, the system comprising:
one or more circuits for use in a server side hub transaction translator of a client server communication system, said one or more circuits being operable to:
communicate a first acknowledgement packet to a server in response to receiving a start setup packet from said server;
communicate an encapsulated setup packet to at least one USB device based on said communicated first acknowledgement packet; and
communicate, to said server, a second acknowledgement packet that is received from said at least one USB device in response to receiving one or more complete setup packets from said server.
12. The system according to claim 11 , wherein said client-server communication system is capable of handling USB 1.1 protocol packets.
13. The system according to claim 11 , wherein said one or more circuits are operable to communicate said encapsulated setup packet to said at least one USB device at a client side of said client server communication system via a client side hub transaction translator.
14. The system according to claim 11 , wherein said client-server communication system is capable of handling USB 2.0 protocol packets.
15. The system according to claim 11 , wherein said one or more circuits are operable to receive one or more complete setup packets from said server based on said communicated first acknowledgement packet.
16. The system according to claim 11 , wherein said one or more circuits are operable to communicate not yet acknowledgement packet to said server, if said server side hub transaction translator has not received said second acknowledgement packet from said at least one USB device.
17. The system according to claim 11 , wherein said at least one USB device comprises a USB interface that is USB 1.1 protocol compliant.
18. The system according to claim 11 , wherein said server comprises a USB interface that is USB 2.0 protocol compliant.
19. The system according to claim 11 , wherein said one or more circuits are operable to communicate said encapsulated setup packet to said at least one USB device via an Ethernet link.
20. The system according to claim 11 , wherein said one or more circuits are operable to receive a second acknowledgement packet from said at least one USB device via an Ethernet link.
