VirtualBox USB Device Filters & OS crashes

[lance-link]

I used the following procedure to successfully install VirtualBox 5.1 in a Fedora 24 Host and Windows 7 Guest.
However, the list of USB Device Filters is cleared after a reboot/shutdown, and the Guest OS crashes frequently. The shared folder configuration is permanent. If I execute "# /usr/lib/virtualbox/vboxdrv.sh setup" then I can reconfigure USB Device Filters, and the guest doesn't crash. How can I make the list of USB Device Filters permanent and stop the Guest crashing? Fedora data is encrytpted and the default machine folder is /home/Documents. Otherwise, defaults are used.

Never mind the post.

From the repititive nature of the comments and cryptic responses, it looks like people don't get much useful help.

Obviously the users and especially the moderators don't know what the SPAM_SEARCH they are doing.

From the repititive nature of the comments and cryptic responses, it looks like people don't get much useful help.

Especially not the ones who don't provide any data to work with, e.g. a log, or a screenshot, plus ask questions that are evidently covered by the user manual (e.g. how to configure a permanent USB filter, section 3.10.1 in the user manual).
