Table 143 show usb device Field Descriptions
Field Description
Device handle Internal memory handle allocated to the device.
Device Class code The class code supported by the device.
This number is allocated by the USB-IF. If this field is reset
to 0, each interface within a configuration specifies its own
class information, and the various interfaces operate
independently. If this field is set to a value between 1 and
FEH, the device supports different class specifications on
different interfaces, and the interfaces may not operate
independently. This value identifies the class definition used
for the aggregate interfaces. If this field is set to FFH, the
device class is vendor-specific.
Device Subclass code The subclass code supported by the device. This number is
allocated by the USB-IF.
Device Protocol The protocol supported by the device. If this field is set to 0,
the device does not use class-specific protocols on a device
basis. If this field is set to 0xFF, the device uses a
vendor-specific protocol on a device basis.
Interface Class code The class code supported by the interface. If the value is set
to 0xFF, the interface class is vendor specific. All other
values are allocated by the USB-IF.
Interface Subclass code The subclass code supported by the interface. All values are
allocated by the USB-IF.
Interface Protocol The protocol code supported by the interface. If this field is
set to 0, the device does not use a class-specific protocol on
this interface. If this field is set to 0xFF, the device uses a
vendor-specific protocol for this interface.
Max Packet Maximum data packet size, in bytes.
