That is correct.
The keyboard
must have the circuitry for both.
Even if achieves the PS/2 connector, by a USB->PS2 adapter, it still has to be built for it.
You can't just take any USB Keybaord or Mosue and pop on an adapter. There are some out there that are USB only.
It's not like PS/2 and DIN5 (AT), those were as far as I know completely compatible, just with different pin outs. USB and PS/2 are not compatible at all, even with a different pin out.
That said, your MS keyboard is probably okay for both, there's a possiblity the adapter is just broken.
