Abstract
Abstract An apparatus, architecture and method for enabling the debugging of USB OTG devices under development is provided herein. An intelligent router ( 100 ) provides the capability to connect to a USB Dual Role Device (DRD) ( 102 ) under development, and obtain debugging information related to the USB interfaces, while also presenting a complete USB OTG compatible interface to another attached USB apparatus ( 106 ). The intelligent adapter ( 100 ) filters data transmitted by DRD ( 102 ), and passes data to attached PC ( 104 ) in a debugging setup.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
88 words
A USB OTG intelligent router comprising: a first connection point for communicating with a first USB OTG apparatus using a virtual USB OTG interface and a virtual debugging interface; a second connection point for communicating with a computer using a debugging interface wherein said intelligent router appears as a peripheral with respect to said computer; and a third connection point for communicating with a second USB OTG apparatus wherein said intelligent router appears to said second USB apparatus as one of a USB device and a USB host.
Claim 2
Dependent Claim
88 words
A USB OTG intelligent router comprising: a first connection point for communicating with a first USB OTG apparatus using a virtual USB OTG interface and a virtual debugging interface; a second connection point for communicating with a computer using a debugging interface wherein said intelligent router appears as a peripheral with respect to said computer; and a third connection point for communicating with a second USB OTG apparatus wherein said intelligent router appears to said second USB apparatus as one of a USB device and a USB host.
Claim 3
Dependent Claim
92 words
The USB OTG intelligent router of claim 1 , further comprising: a first logical switch coupled to said first connection point; a USB host controller coupled to said first logical switch; a micro-processor coupled to said USB host controller; a first USB function controller coupled to said micro-processor and to said second connection point; a second USB function controller coupled to said micro-processor and to a second logical switch; a third logical switch coupled to said second connection point; and a USB Hub coupled to said first, second and third logical switches.
Claim 4
Dependent Claim
68 words
The intelligent router of claim 2 , wherein said micro-processor is configured to: pass UDB OTG Host Negotiation Protocol requests bi-directionally between said first USB OTG apparatus and said second USB OTG apparatus; determine a configuration of said first USB OTG apparatus, said configuration being determined by said Host Negotiation Protocol; and perform configuration of said intelligent router based upon said configuration of said first USB OTG apparatus.
Claim 5
Dependent Claim
87 words
The intelligent router of claim 3 , wherein said configuration of said intelligent router comprises: enabling said USB hub, disabling said USB host controller and copying data bi-directionally between said first USB function controller and said second USB function controller if said first USB OTG apparatus is configured as a USB host; and enabling said USB host controller, disabling said USB hub and configuring said second USB function controller to present a USB OTG interface if said first USB OTG apparatus is configured as a USB device.
Claim 6
Independent Claim
106 words
A method of debugging a first USB OTG apparatus comprising: passing, by a USB intelligent router, USB OTG Host Negotiation Protocol requests bi-directionally between said first USB OTG apparatus and a second USB OTG apparatus; determining whether said first USB OTG apparatus is configured as a USB host or a USB device, said configuration being determined by said Host Negotiation Protocol; copying data bi-directionally between said first USB OTG apparatus and said second USB OTG apparatus if said first USB OTG apparatus is configured as a USB host; and presenting a USB OTG interface if said first USB OTG apparatus is configured as a USB device.
Claim 7
Independent Claim
106 words
A method of debugging a first USB OTG apparatus comprising: passing, by a USB intelligent router, USB OTG Host Negotiation Protocol requests bi-directionally between said first USB OTG apparatus and a second USB OTG apparatus; determining whether said first USB OTG apparatus is configured as a USB host or a USB device, said configuration being determined by said Host Negotiation Protocol; copying data bi-directionally between said first USB OTG apparatus and said second USB OTG apparatus if said first USB OTG apparatus is configured as a USB host; and presenting a USB OTG interface if said first USB OTG apparatus is configured as a USB device.
Claim 8
Dependent Claim
25 words
The method of claim 5 further comprising: routing data from said first USB OTG apparatus over a virtual debugging interface to a development host computer.
