I had this same problem, since these two projects seem like a great pair. The problem is Qubes' dom0 has no USB devices attached in a default set up - it all goes through the 'sys-usb' and there's no way to pass USB to dom0 (I think that's a security concern). One could implement a daemon in dom0 to watch a file or device in sys-usb. Otherwise, running this in one of qubes' VMs just shuts down the VM. I might work on this if you're still interested.

Did anyone get it to work?

adamthiede commented 2 years ago

I've yet to try out the latest Qubes release but thanks for reminding me. It might work better since I believe it's based on a much newer OS.

anonaddict commented 2 years ago

I don't think the OS is the issue. The issue is very likely the way Qubes is built around virtualization and compartmentalization https://forum.qubes-os.org/t/yubikey-usbkill/10053
