What's is this? An SMD Voltage Regulator?
Ti part marking lookup yields a result with LFNB. This leads to LP3981IMM-3.3/NOPB, which seems to be compatible with your pictures in terms of pinout.

Identify SMD component on USB hub
EDIT: Based on additional Info my answer is most likely wrong, since according to Chipyto pin 2 is at 5 V, which would not make sense with this part.
I'd say it is one of these two:
Both are marked ...

Identify SMD component on USB hub
It's a Sinopower SM2413PSAN P-Channel MOSFET.
I can't find a picture of the SM2413PSAN, but if we look at other MOSFETs from Sinopower, like the APM2300CAC-TRG, we can see that the marking style ...

What sort of transistor is this?
It can't be really old since ST isn't that old. Mid to late 1980s at the earliest. You can look up when SGS and Thomson got together. Perhaps 1988 is the year of manufacture.
So probably silicon (you ...
