No iphone or anything else connected via USB at any time.
I just got another kernel panic and it's worse than the previous ones. The other times I was able to get everything working after rebooting.
This time, I can't load any VMs at all; the one VM I had open when the kernel panicked shows as aborted and can't be opened, giving "exit code 1" and
Result Code: NS_ERROR_FAILURE (0x80004005)

Interface: IMachine {5eaa9319-62fc-4b0a-843c-0cb1940f8a91}
the other VMs also won't open either. (all Windows guests)
Trying to look at Settings, it says "failed to access the USB subsystem could not load the host USB proxy service VERR_GENERAL_FAILURE, and then the details are

When I close the bouncing icon in the Dock for the VM that won't open, I get:
Kernel Driver Not Installed (rc=1908)
Make sure the kernel module has been loaded successfully
VBox may have been developing problems before this last kernel crash, I've been having trouble with all but one VM not having their remote desktop ports available -- and it was the one where RD did work that now is aborted.
Dunno. Will poke at it further. I've sent all the reports to Apple routinely. Can post more here if there's something that would be useful to someone.
