MimioTeach and Mimio Xi can go a maximum of 32' (10 meters) with an unpowered or powered hub between the two cables. Lengths beyond that have not been tested, though using as many powered hubs as you want could provide a longer range (again, not approved by Mimio). If using the MimioCapture, the 16' cable must be attached directly into the computer—unless you use one powered hub, then you can go up to 32'. The maximum length cable for the MimioView is 25'. The 10' USB cable that comes with the MimioView plus a 15' USB extension cable totals 25' USB. 2.0 High Speed Extension: No power cable required.
