Netgear router silkscreen designator 'B'

[Sjokolade]

Hi

I crossflashed a Netgear router to a bigger model and I'm going to solder in an usb port that this smaller model did not have, there are 3 components missing and 2 of them has silkscreen designator B2 and B3 - anyone know what this components are supposed to be ?

The missing cap C195 I found out is a 16V 100 microfarad.

They are ferrite beads. You can just put 0 Ohm resistors or jumpers there.
