@Sahaj0321: Check this resource: https://community.spiceworks.com/topic/2102507-passthrough-integrated-webcam-to-hyper-v-guest
If you edit the Windows Policy (gpedit.msc) in that article, it will allow you to pass a webcam as a resource via RDP. The issue I'm running into is that the Hyper-V RDP mechanism is not allowing me to choose that as a resource to my Ubuntu guest OS. If you find a solution for this final mile, let me know.
