Detecting them from their Hawking Radiation is another possibility although I'm not sure if that has yet been accomplished.

It likely will never be accomplished, as Hawking radiation involves purely theoretical, tiny particles and anti-particles that usually form in empty space and nearly instantaneously annihilate themselves. Hawking radiation involves the standard appearance of such particles at the event horizon of the black hole, except this time gravity pulls in one of the particles allowing the other to escape. The particle pulled in must have negative energy due to the Conservation law, meaning that negative particle would annihilate energy within the black hole, causing it to slowly "evaporate".
The normal annihilation of such virtual particles gives off a minute amount of energy (more precisely, it releases borrowed energy) that CAN be experimentally detected through what is known as the Casimir effect. However, without that annihilation, proving the existance of such particles will likely remain impossible for some time to come.
