One of my nRF52840 Dongle's component is missing

Hi, I don't understand enough about electrical, but i found that a little piece of component in my nRF52840 dongle was gone.

It was something in this position:

It was the FB2, and this makes my dongle not detected on my PC

Since I don't know what component is that, is it okay just to short it?

This is a ferrite bead for noise suppression. Without this, the USB ground won't be connected to the dongle's ground. It's ok just to short it.

Thank you!
