DDK USBView sample bug

There is a bug in the usbview DDK sample when they display the
wMaxPacketSize information for
high-speed isochronous and interrupt enpoints.
In the current sample (3790.1218) the just display the wMaxPacketSize field.
In the description of this
field in the USB 2.0 spec, it says:

For all endpoints, bits 10..0 specify the maximum packet size (in bytes).
For hight-speed isochronous and interrupt endpoints, bits 12..11 specify the
number of additional transaction
opportunities per microframe.

Since I do not know where to file DDK bug report I am posting this on this
