(Case 413233)
Deborah,
At this point we would advise trying to connect to the board with a shorter USB cable directly into the upper left of the ActivBoard. If that is able to work, you could attempt to use any of the solutions outlined in Articles 10414 and 10440 from our Promethean Knowledge Base (www.prometheanKB.com) in regards to extending the distance of that connection. Be advised that, given the issue presented in this case, an externally-powered version of some of the extension cabling presented may be a more feasible solution.
