HID forward support on vhidmini2 driver sample

Question

Hi All,

I am new to windows driver development. I am trying to work on HID forwarding to remote machine using Virtual HID driver. While exploring I came across of vhidmini2 driver

https://github.com/microsoft/Windows-driver-samples/tree/616b1914cf05f0aea9c40b10009bd7be0354c28b/hid/vhidmini2

I am able to bring up the vhidmini2 on windows 11. But the driver does not support the HID forwarding feature to Remote machine using RDC method. I tried to go through the documentation on supporting HID forward on virtual HID device. But did not find enough information. I am looking for answers for the below questions:

Questions 1: Is it possible to support HID forwarding to RDP server on Vhidmini2 driver sample?

Questions 2: If yes, can you point me to the right resources from where I can learn and implement the feature in this driver? If there are any standard procedures to be followed to support this feature, do let me know.

Thanks in advance!

Hello Dayananda Kempapura Thippanna,

Thank you for posting in Q&A forum.
Here are the answers for your references.

1. Yes, it is possible to support HID (Human Interface Device) forwarding to an RDP (Remote Desktop Protocol) server using the Vhidmini2 driver sample. However, this requires significant modifications to the driver to handle HID input and forward it appropriately over RDP.
2. Vhidmini2 Driver Sample on GitHub:
