When I plug my Curve into either of my computers, I get this message:

USB charging current is not sufficient. Verify that your handheld is connected to a powered USB charging source and that the proper USB driver is installed.

Where can I find the correct driver?

If you install Blackberry Desktop Manager you will get the correct chargers.

And welcome to the forums!

Also, here is a link to a forum where someone was able to find the correct driver so they could chrage their BlackBerry without installing Desktop Manager:

So with DM installed it will charge the BB in the same manner as a wall charger ?

Yes and no. On mine, the USB charging take a little longer to get to 100%, however I "feel" I get a better charge that lasts longer that way (like a good trickle charge rather than a fast quick charge, you know, sometimes slower is better).

But that is just my "feeling", I would love for someone to confirm it for me.

It will be slower simply because the USB port delivers a lower voltage then the AC charger. AFAIK it is 3.3v vs 5v.
