The USB 2.0 Device is covered in the USB 2.0 Spec. 

For the USB-IF Compliance program the Device should under go the following test:

• High Speed Electrical
• Full/Low Speed Signal Quality
• Inrush
• Back Voltage
• Interoperability (Goldtree)
• USBCV
• Power consumption
• ADP detection
• Battery Charging 1.2 Capabilities

USB 2.0 Device	High Speed Electrical	Full Speed Signal Quality	Low Speed Signal Quality	Inrush	Back Voltage	Interoperability Goldtree	USBCV	Power consumption	Battery Charging tests
High Speed	Y	Y	F	Y	Y	Y	Y	Y	F
Full Speed		Y	F	Y	Y	Y	Y	Y	F
Low Speed			Y	Y	Y	Y	Y	Y	F

Y = Always required
F = Required if feature is supported

• If the product support Battery Charging 1.2 the product must under go the Battery Charging 1.2 compliance tests
• Make sure that the device have the required bypass capacitance in order to make ADP detection possible
  When submitting for USB-IF Compliance also take care of the following:

• Check that the product complies with the USB-IF requirements of the USB-IF Compliance website
• Complete the VIF file. You can download the USB Vendor Info File Generator at www.usb.org 
• Make sure that the used cables and connectors are USB-IF certified !!!
