[edk2] HID descriptor parsing

[Ulysses Mckibbens]

Hi,

Where is the HID descriptor parsed in the UsbBusDxe driver? 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?

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.

Hi Tian,

Which driver handles the keyboard devices? we did see that in the mouse
driver.
