The defendants are charged with conspiracy to possess with intent to distribute a cocaine base of 280 grams or more.
They were due in federal court in Dallas tomorrow, but that court date was reset, and they'll now go to trial August 24.
They were charged after an investigation that began before New Years Day in 2009 and wrapped up earlier this year.
FBI officials installed a camera on a light pole in the Budget Inn parking lot and recorded activity at the motel for more than a year.
Assistant US Attorney Brandon McCarthy says most of the defendants were caught on camera selling drugs to undercover agents.
If convicted, each defendant faces a sentence of ten years to life in prison, and up to a $10-million fine.
