See the Remarks section. Boot video device pcieport-driver A filter service callback can be configured to modify the input data that is transferred from the device’s input buffer to the class data queue. The HID source driver links to Vhfkm. The first implementation would be windows only, although I plan on making a cross-platform solution.
