USB physically disabled - how to re-enable.
Posted: Sun Dec 29, 2019 1:20 pm
Hi,
I've picked up a pair of Fitlet2 devices from an old project, the person who worked it is no longer present so I'm pretty blind. One of these devices is completely dead - but the other is a bit more interesting. It works perfectly other than the USB ports are completely non-functional.
From what I can see on the motherboard, there has been some tampering going on to physically remove some SMD components - I suspect this device was public facing which is why someone brute-forced the USB ports out. This is both USB2 and USB3 ports.
It looks like the following SMD components are missing:
C31
C491
U27
C364
C482
U24
I think that's all, but I'm happy to provide high-res photos if someone think they know exactly what might've been done.
I believe U27 and U24 should be MIC2039EYM6 chips (power distribution), but I'm at a loss to what the other 4 components (capacitors??) should be. Is it possible to get values (sizes, ratings etc) for C31, C491, C364 and C482?
