Class Analysis Options are continually added to the repertoire of GraphicUSB. The options work identically with the complete Packet-Master range of Analysers. The following classes are now available:

• Audio Class (V1.0, V2.0)
• Communications Class
• Hub Class
• Human Interface Devices (HID)
• Image Class and Media Transfer Protocol (MTP)
• Mass Storage Class
• Printer Class
• Test and Measurement Class
• Vendor Class
• Video Class (V1.0, V1.1)
• ...see full details below...

Registering an option allows Graphic USB to display Class transfers in a more readable form.

Example (Human Interface Device Class)

The screen shot above shows the analysis of a typical HID Report Descriptor.

The shot below shows the results of the built-in 'HID Report Descriptor' parser. Each report defined by the Report Descriptor is identified and displayed.

With the HID Class Analysis enabled, each HID report is identified, and the contents analysed.

Examining the analysis of existing devices is an excellent way to learn how a class works, and it has never been easier to reveal the building blocks, than with GraphicUSB.
