We had a similar problem on the way to Yellowstone last summer (2010 Silverado 2500 - integrated controller). Trailer shop determined trailer brakes ok, so it was the truck.
Went to Spearfish GM. They also "got power" when activating brake at the connector.
Turns out it was the brake controller fuse. Even though it was pushing some voltage, not enough to activate brakes.
Bad connection on trailer pig tail was causing over compensation in brake circuit and blew fuse. cleaned pigtail, electrical goo in plug, new fuse - all better.
Hope this helps.
