I have the 4 Samsung Galaxy Tab A tablets and the Motorolla tablet working on our classroom machine.
The drivers for these devices are in Assignments>TdeLaubenfels>CSC355. These devices also worked on every lab machine I tried (which is not all 21 systems). My Asus tablet also works on all these systems.
I ask that you install your tennis scoring app on one of these Samsungs or the Motorolla, by the end of the day on Wednesday.
Please reply to this post to let us all know what devices you have running on what systems.
