An apparatus, architecture and method for enabling the debugging of USB OTG devices under development is provided herein. An adapter module ( 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 adapter module ( 100 ) filters data transmitted by DRD ( 102 ), and passes data to attached PC ( 104 ) in a debugging setup.
