UsbBusDxe driver is a bus driver who is used to enumerate attached devices and start their corresponding device drivers.
So you couldn’t see HID parser in UsbBus driver. You have to see it in usb device drivers. UsbMouseDxe/MouseHid.c is such sample for how parsing HID items.

I am using a Minnowboard Max with 0.81 firmware and I am trying to debug the HID descriptor attributes for a device I'm writing a driver for. Any pointers?
