UsbKbDxe driver in MdeModulePkg/Bus/Usb handles usb key board devices. Note we don’t parse its HID descriptor in this driver, we only use SET_REPORT request to enable Keyboard’s LED.
If you need to parse HID items, you can refer to the logic in usb mouse driver and write a new one. PS: UefiUsbLib in MdePkg/Library provides some library APIs to provide HID services.

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? ------------------------------------------------------------------------------ _______________________________________________ edk2-devel mailing list edk2-de...@lists.sourceforge.net<mailto:edk2-de...@lists.sourceforge.net> https://lists.sourceforge.net/lists/listinfo/edk2-devel _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
