Only a moderate insertion/removal force is needed (by specification). USB cables and small USB devices are held in place by the gripping force from the receptacle (without the need for the screws, clips, or thumbturns that other connectors require). The force needed to make or break a connection is modest, allowing connections to be made in awkward circumstances or by those with motor disabilities.
For most users, this is a good thing. But in situations like in a DJ booth, it's dangerous. I've seen two good solutions. You can use aluminum duct tape, cut it the length of the male plug, and wrap it around to create a snugger fit. Alternatively, you can use something like a toothpick as a wedge. Personally, I carry a roll of painters tape and tape down the cables to the table just outside the computer.
