Abstract
Abstract A method for recognizing an overcurrent event in a universal serial bus is described. The method comprises the step of monitoring communication between a first layer and a second layer of the software layers of the universal serial bus. The method further comprises the step of generating a data structure configured to store the communication between the first layer and the second layer. The method also comprises the step of parsing the data structure to locate a data transition indicating the overcurrent event.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
74 words
A method for recognizing an overcurrent event in a universal serial bus, the method comprising the steps of: (A) monitoring communication between a first layer and a second layer of software layers of the universal bus; (B) generating a data structure configured to store the communication between the first layer and the second layer; and (C) parsing the data structure, the parsing locating a data transition in the data structure indicating the overcurrent event.
Claim 2
Independent Claim
74 words
A method for recognizing an overcurrent event in a universal serial bus, the method comprising the steps of: (A) monitoring communication between a first layer and a second layer of software layers of the universal bus; (B) generating a data structure configured to store the communication between the first layer and the second layer; and (C) parsing the data structure, the parsing locating a data transition in the data structure indicating the overcurrent event.
Claim 3
Dependent Claim
22 words
The method of claim 1, wherein Step (A) further includes inserting a filter driver between the first layer and the second layer.
Claim 4
Dependent Claim
13 words
The method of claim 2, wherein the first layer comprises a hub driver.
Claim 5
Dependent Claim
15 words
The method of claim 2, wherein the second layer comprises a universal serial bus driver.
Claim 6
Dependent Claim
23 words
The method of claim 1, wherein Step (B) further includes storing hub status information communicated between the first layer and the second layer.
Claim 7
Dependent Claim
23 words
The method of claim 5, wherein Step (B) further includes storing port status information communicated between the first layer and the second layer.
Claim 8
Dependent Claim
36 words
The method of claim 1, wherein Step (C) further includes a user interface configured to examine the data structure to locate the data transition, the user interface notifying a user when the data transition is detected.
