Hitachi interactive projectors and Data Harvest Easy Sense Conflict?

[richardg7vyi]

Just had a really weird one here. We have a recently installed Hitachi Interactive Projector running Starboard software in physics lab on a teachers windows 10 pc. This is one of many we now have around the site in different faculties. The department uses Data Harvest Easy sense boxes for some experiments etc. When the teacher has connected the Easy sense box to this classroom computer via its USB port it seems to have caused some sort of conflict with the projector usb comms. Teacher reports something along lines of a message saying cannot detect projector and also the easy sense box cannot be found by the data harvest software. This happened with 2 different Easy Sense boxes which now appear to have been rendered non operational when connected to another PC. Now proceeding with caution as it appears it may have blown £200 worth of easy sense boxes already so it's difficult to prove whats happening without risking damage to some more.

 

Has anybody else experienced any sort of issue software or hardware wise between these boxes and Hitachi starboard software or projectors as it's nothing I've seen before?

I haven't had experience with either but it kind of sounds like that maybe the root USB hub on the PC is being overloaded. It could be having that both devices connected to the PC at once is putting too much of a power draw on the USB ports.

 

Have you tried using a powered USB hub?

I would check which usb ports you are plugging in to. USB3 is notorious of being difficult with equipment.

If you have USB 2 ports try using them and see if the problem persists.
