I was wondering about the possibility of repair.
I'm not likely to start replacing BGA chips or anything, but do USB ports tend to
have surge protection components or similar fitted? I might be up for
taking a look at that if so. I have some spare ports round the front of the PC but would prefer to keep using the rear ones if possible.

I am quite impressed that only this went, and that everything else seems
to be working fine. But I was wondering about the possibility of repair.

I suppose if it had failed short circuit that would stop the port working:

Just removing it would be a test to see if it fixes the problem, although that would leave the port unprotected from being zapped by static so better to replace it.
Hi All - a bit of a longshot, but you never know...
We had a fairly impressing lightning storm a week or so ago. Just as the storm approached, and I was thinking of taking some sort of
'precautions' ...
there was a small white 'flash' near the back of my main PC.
I know about the serious effects lighting can have, and decided to shut everything down until the storm had passed. When I got back up and
running,
it seems as though one of the rear USB ports on my motherboard has
blown.
It was connected to a DAC and then my audio at the time of the supposed strike (I guess it could be coincidence that this failed as a storm was approaching... hmm).

to be working fine. But I was wondering about the possibility of repair.
