I seem to recall that in 3e you could suffer a mishap if you didn't meet the UMD DC to activate a scroll. Is that still the case in 3.5e since I can't find anything on that? Does that mean that if you don't meet the DC you simply can't activate the scroll? If that's the case, is there any chance of a mishap?

I know that if your caster level is lower than the scroll's caster level you require a caster level check, but the UMD skill description doesn't specify a caster level.

Thanks!

If the user meets all the requirements noted above, and her caster level is at least equal to the spell’s caster level, she can automatically activate the spell without a check. If she meets all three requirements but her own caster level is lower than the scroll spell’s caster level, then she has to make a caster level check (DC = scroll’s caster level + 1) to cast the spell successfully. If she fails, she must make a DC 5 Wisdom check to avoid a mishap (see Scroll Mishaps, below). A natural roll of 1 always fails, whatever the modifiers.
Determine Effect: A spell successfully activated from a scroll works exactly like a spell prepared and cast the normal way. Assume the scroll spell’s caster level is always the minimum level required to cast the spell for the character who scribed the scroll (usually twice the spell’s level, minus 1), unless the caster specifically desires otherwise.
The writing for an activated spell disappears from the scroll.
Scroll Mishaps: When a mishap occurs, the spell on the scroll has a reversed or harmful effect. Possible mishaps are given below.
• A surge of uncontrolled magical energy deals 1d6 points of damage per spell level to the scroll user.
• Spell strikes the scroll user or an ally instead of the intended target, or a random target nearby if the scroll user was the intended recipient.
• Spell takes effect at some random location within spell range.
• Spell’s effect on the target is contrary to the spell’s normal effect.
• The scroll user suffers some minor but bizarre effect related to the spell in some way. Most such effects should last only as long as the original spell’s duration, or 2d10 minutes for instantaneous spells.
• Some innocuous item or items appear in the spell’s area.
• Spell has delayed effect. Sometime within the next 1d12 hours, the spell activates. If the scroll user was the intended recipient, the spell takes effect normally. If the user was not the intended recipient, the spell goes off in the general direction of the original recipient or target, up to the spell’s maximum range, if the target has moved away.

Above is the pertinent section from the SRD. It is listed under Magic Items>Scrolls rather than under the UMD skill description.

Just to clarify your stance, you are saying that when trying to activate a scroll with UMD, you must make a caster level check if you posess no caster level (for example, you are a rogue). You would thus, roll a d20 and add nothing? The reason I ask is that it can be argued that non-casters cannot make caster level checks at all.
 

Upon re-reading the UMD skill description, it appears there is only chance of a mishap when "activating blindly". In all other uses of the skill, failing the check simply means you fail to activate the item. Failing with a natural 1, of course, has an additional penalty.

Right. In 3E, UMD to activate a scroll had a fixed DC, and provided a caster level based on your check result, allowing for the possibility of a successful UMD check, but a mishap through insufficient caster level.

In 3.5, UMD to activate a scroll has a variable DC dependent on the scroll's caster level, and thus you either successfully activate the scroll, or you don't activate the scroll at all. No chance of mishap.

If you fail to identify the scroll could you get another try? or would have to wait for X rounds/mins/hours/days/weeks/lvls? lol

Fail to activate, you mean?

If you fail to activate the scroll (unless you get a mishap, which can't happen with UMD anyway), nothing happens... the scroll is not expended. You can try again next time you have a standard action available (or whatever the activation time of the scroll is).

On a slightly related note (in so far as it involves UMD), what happens when a character possesses ranks in both UMD & UPD (Use Psionic Device), & the campaign world uses magic-psionic transparency (the two interact with each other as equals, etc.)? Would the character be able to combine the skill ranks for a higher base skill (but still limited to level+3 or /2 for max skill ranks)?

Hope it's not too much of a highjack. :\
