USB doesn't work anymore (after using Virtualbox guest additions?)

Hi, my host is Ubuntu 16.04, and I run VirtualBox 5.2 with extention pack installed.
I don't know if it's just a coincidence, but everything was working fine 'till this morgning, when i try to edit resolution of a guest vm installing "VirtualBox Guest Additions".
The resolution now works well, but VirtualBox can't see anymore any device connected to my PC USB ports.
Can anyone help me?
Thanks.

The GAs have nothing to do with USB. Nothing more can be said without a VM log.

With the VM fully shut down, right click and "Show Log" in the GUI, save "VBox.log" (no other file) to a zip, and attach the zip here.

You didn't attach a log, please try again. Remember to ZIP the log first before uploading it (see the "Upload attachment" tab below the reply form).

I told you the exact name of the log I wanted, so I'd prefer to see only that one.

mpack: That would involve something called
"reading the reply"...

Not to keep beating on a dead horse, but you
still need to read
carefully the instructions. Since you're new, I'm going to let this one slip
, but in the future, attachments that are NOT ZIPPED are going to be removed:

You have enabled USB3 for an operating system that doesn't have support for USB3. Did you install the additional drivers required? See:
USB basics and troubleshooting,
#6: Guest support.
BTW, you have 2 cores on your host, and you've assigned both to your VM. I would reduce the number of CPUs assigned to the guest down to 1.
