I’m debugging HIDClass driver in windbg. It be helpful to see report descriptor in windbg but I couldn’t find windbg command to get report descriptor from device PDO.
Do you know about such a command ?

The report descriptor is not stored in memory. It takes a USB control
request to fetch it.

Is there any tool that comes with WDK that i can use to view report descriptor.
Try the !devext command on the HID PDO or FDO device extension. If
there is a structure in a header that defines the report descriptor (I
don’t think there is since it is a compacted structure in a byte stream)
then you can use dt. There is also !hidppd, but I think that is now
obsolete.
