This used to work with a previous version, but has been broken since the update. I have a USB 3.0 128GB Patriot stick that I often use to transfer files. I also have a Delock USB 3.0 CFast reader that I am using. I had created filters for both in the earlier version and they worked fine, but now they fail to attach the device when I select them from the USB list of filters.

Host OS is Windows 10 and the guest OS is Ubuntu 16.04 64-bit, running on a laptop with an i7 CPU.

I have also tried editing the USB filters, or making them enabled by default, but any attempt to change them gets this error when you click OK to save:

Failed to save the settings.

Empty or null bridged interface name is not valid.

You need to re-read #4: USB Filters of the USB basics and troubleshooting thread. You have too many values defined.

What does that mean? Select what from where? Are you maybe confusing the "On-the-fly" with the "filter" method? See #2: Capturing a USB device in VirtualBox, same thread.

That's because there's something wrong with your settings. It actually tells you which part.

PS. I didn't see the device(s) being plugged as described in #8: Asking for help, did you follow the instructions exactly?
