Hello, i've problems with rdp. I have virtual driver USB HID mouse and keyboard and the program that interacts with it. When im start my program it's connect to virtual hid usb driver and i can send message "press any keys or drag mouse to x, y cords". When im start host pc without rdp it's work fine, but when i try to connect with rdp to this host machine, my program success connected to hid usb driver, but it's not respond to my messages. in my program i send messages via
HidD_SetFeature(FDevHandle, buffer, length + 1);
It turns out that the RDP is blocking the driver, how fix this?

- use UMFD/KMFD driver based on HID Minidriver Sample (UMDF version 2) (or yours emulator driver) only when you disconnected from RDP session (and rdp drivers disappear) with
sleep 5 | tscon.exe 2 /dest:consolecommand, executed as administrator from PowerShell console (to make available GUI without RDP and has control on it via driver) - use another kernel upperfilters driver to control RPD drivers only if that drivers are available (only while you stay logged in rdp session), moreover you have to use exactly device_id == rdp_device_id to inject strokes via sendinput interfaces, for example, I experimented successfully on Windows Server 2022 with:
- Classic Interception signed driver with Interceptor wrapper
- Good constructed native/managed InputEmulator driver
- Classic Interception signed driver with Interceptor wrapper
- use UMFD/KMFD driver based on HID Minidriver Sample (UMDF version 2) (or yours emulator driver) only when you disconnected from RDP session (and rdp drivers disappear) with
