USB Filter Change -> VM Black Freeze

Post by balint » Tue May 21, 2019 8:16 am

Host: Linux Mint 19.1 - 64 bit, Cinnamon + VirtualBox 5.2.30 respectively 6.0.8 + appropriate Extension Pack + membership of vboxusers group
Guests: Windows10 Home 64-bit + Windows 7 Prof 32-bit + both with Guest Additions - both worked well until I changed a USB filter

My two well-functioning virtual Windows-es (7 and 10) were crashed at the same time: only a black screen appears at startup, nothing more. I only changed one of the USB filter settings for one machine (the virtual machine was standing), but both virtual Windows-es died. Now they can only be shut down forced, and even the Linux Mint itself. Zombie processes run in the background that cannot be killed neither from a terminal.

I tried to reinstall the VirtualBox and also the VMs with its setting files (*vbox, VirtalBox.xml), I made several attempts. However exclusively the reinstalling of the Linux Mint system helped, then my VMs worked again. Unfortunately when I set one of the USB filter, I've got back the same black freeze again.

How could I repair my VMs without reinstalling the Linux?

This is a very technical question. Was going to suggest you raise it on the VBox Forum, but I see you have.

Frankly, unless someone here happens to have had the exact same issue, VBox Forum is the right place.

In fairness to socratis, per their forum rules, you're supposed to have included most of that in the OP.
