NASA seems plan EVAs directly from Orion for EM-2 (from 1:35 in the video).

http://www.universetoday.com/88434/human-mission-to-an-asteroid-the-orion-mpcv/Per Lockheed:Logistically, the Orion MPCV could even support doing an EVA from the hatch on the capsule.“We have a hatch that is big enough that an astronaut in a space suit can get out,” Hopkins said, “and the internal systems in the spacecraft are designed to tolerate the cabin being depressurized. We don’t rely on air circulation to carry the heat away from the electronics – they have their own cold plates to take the heat away. The knobs are designed to be manipulated with spacesuit gloves on, not just bare hands. A lot of those features just worked out to be pretty applicable to the asteroid mission because it was designed for a similar set of mission requirements.”
marketing words
It is good to know that Orion can not support EVA for missions such as the asteroid rendezvous.

A single Orion would probably not be able to service Hubble, but two Orions...One would stay pretty much standard / unmodified and would hold the crew. The other would be launched without LAS, main engine, maybe even without parachutes and proper heatshield - but with the needed robotic arm(s), ORUs, space suits, etc. and should still be a known quantity wrt life support, EVA, hatch, avionics, and so on.
Actually, this is for a rate sensor unit, which contains 2 TWO gyros.This is literally smaller than a breadbox. Can this really NOT fit into Orion?
Question: Can Dragon support EVA, and if so, what technology is available to Dragon that Orion does not have?
With the Skylab II approach, Hubble, Spitzer, Kepler etc. systems could be re-fitted, refueled etc

Unless someone sticks something like the MMSEV on the Dragon. How is the development of the MMSEV's suit port getting along?

Dragon is a spacecraft and not a fairing for the MMSEV. MMSEV is not a flight project, so there is no real work in developing the suit lock.

I do not need the Dragon (or CST-100) to be a fairing to the MMSEV but a crew delivery vehicle that docks with the granddaughter of MMSEV.
Hubble will be killed off shortly
"sticks something like the MMSEV on the Dragon" implies carrying and not connecting to.
