problems with 3.0 trackers not connecting

hi there! this is my first time asking for support from a reddit so excuse me if i’m bad at explaining.

I have the 3.0 vive trackers & just recently set up my cosmos elite after using the 3.0’s with the quest 2 for like 2 years and after setting up the cosmos only ONE of the trackers fail to connect to steamvr, i checked the dongles and unplugged, replugged, changed USB ports; the whole thing. The trackers are charged. and it’s not broken, as it connects when i plug it straight into the pc. the dongles just don’t work.

Is there any fix to this? Are the dongles broken? is it a software issue?
