"I don't want to trade him," the 85-year-old Devos said of Howard, who is eligible to become a free agent at the end of the season.
Howard has publicly requested a trade from Orlando.
"We like to think we're making headway," Devos said of talks with Howard and his representatives. "But I don't know. He probably won't know until the end and I won't either."
In a related matter, NBA commissioner David Stern said he doesn't think Howard's uncertain future will overshadow the All-Star Game in Orlando in 3 weeks.
The commissioner spoke in Houston, where he officially announced that the All-Star Game would be held there in 2013.
