Universal serial bus assistance engine
A method to interact with a local USB device is disclosed. A message is received from the local USB device. Predetermined information is extracted from a proper subset of the message. The extracted information is transmitted to a local process.
1. A server configured to interact with a remote USB device comprising:
a host controller driver for the remote USB device;
an outbound interface to transmit a configuration for predetermination from the host controller driver to:
1) a message analyzer that is associated with the remote USB device and configured to extract information from a subset of a message comprising a USB HID report associated with the remote USB device based at least in part on the configuration for predetermination, practically implementable by hardware without using an instruction-based processing element; and
2) an assistance engine that is associated with a remote USB host controller and configured to resubmit a USB descriptor to the remote USB host controller after the message analyzer extracts, wherein the resubmission is based at least in part on the configuration for predetermination and a past USB descriptor received earlier; and
an inbound interface to receive a message from the message analyzer for the host controller driver.
2. A server as recited in claim 1 , wherein the message comprises an extracted information from the message analyzer.
3. A server as recited in claim 1 , wherein the message comprises a message from the remote USB device.
4. A server as recited in claim 1 , wherein the message comprises an aggregate of extracted information from a plurality of messages from the remote USB device.
5. A server as recited in claim 1 , wherein the configuration is based on enumeration of the remote USB device.
6. A server as recited in claim 1 , wherein the remote USB device is a USB pointing device.
7. A server as recited in claim 1 , wherein the message comprises an extracted information from the message analyzer, and the extracted information is positional information.
8. A server as recited in claim 1 , wherein the message comprises an extracted information from the message analyzer, and the extracted information is click action information.
9. A server as recited in claim 1 , wherein the configuration of the message analyzer is based in part on a driver local to the server.
10. A server as recited in claim 1 , wherein the configuration of the message analyzer is based in part on a pointing device driver local to the server.
11. A method to interact with a remote USB device comprising:
transmitting a configuration for predetermination to:
1) a message analyzer that is associated with the remote USB device and configured to extract information from a subset of a message comprising a USB HID report associated with the remote USB device based at least in part on the configuration for predetermination, practically implementable by hardware without using an instruction-based processing element; and
2) an assistance engine that is associated with a remote USB host controller and configured to resubmit a USB descriptor to the remote USB host controller after the message analyzer extracts, wherein the resubmission is based at least in part on the configuration for predetermination and a past USB descriptor received earlier; and
receiving a plurality of messages from the message analyzer; and
performing a host controller driver service for the remote USB device.
12. A method as recited in claim 11 , wherein the message comprises an extracted information from the message analyzer.
13. A method as recited in claim 11 , wherein the message comprises a message from the remote USB device.
14. A method as recited in claim 11 , wherein the message comprises an aggregate of extracted information from a plurality of messages from the remote USB device.
15. A method as recited in claim 11 , wherein the configuration is based on enumeration of the remote USB device.
16. A method as recited in claim 11 , wherein the remote USB device is a USB pointing device.
17. A method as recited in claim 11 , wherein the message comprises an extracted information from the message analyzer, and the extracted information is positional information.
18. A method as recited in claim 11 , wherein the message comprises an extracted information from the message analyzer, and the extracted information is click action information.
19. A method as recited in claim 11 , wherein the configuration of the message analyzer is based in part on a driver local to a server.
20. A method as recited in claim 11 , wherein the configuration of the message analyzer is based in part on a pointing device driver local to a server.
