Hi Larz,
Thanks for your interest in this matter.
USB port assignments may vary, ProductID, VendorID and serial# don't.
I can now -on the fly- determine if an inserted USB stick :
- is mine ?
- is who's ? (providing an authorized list of serials, that can be hard-coded or encrypted))
- is authorized to access a given PC? (between hours, certain days...)
- is made by which vendor...(inclusion , exclusion list)
(And the stick may have no data at all, freshly formatted.)
Possible applications are numerous.
You can do the same with other USB connected devices like the BBC micro:bit, all be it in a slightly different manner.
