I tried using the 1.36 Virtualbox update again today.
If the USB setting is anything other than USB 1.1, the guest Windows 10 vm fails to start with the NS_ERROR_FAILURE of the thread title.
I can set USB 1.1, get the VM running, and then update the guest vm to the 1.36 guest additions. This guest additions update succeeds, but I still cannot start the guest VM with a higher level of USB support. I tried with or without a device filter in place limiting access to a USB webcam. When I try the win10 camera app using USB 1.1, the app complains that the camera is reserved for some other program.
I’m not having an issue with secure boot, and my kernel module and startup info looks like the above success case.
Ok, I did not fully understand the question on Extensions - I see that I am running a 1.32 Extension Pack and I am now looking into updating that. That’s likely the issue.
