First of all, I have no problems when I try to connect the Mbot Ranger to the computer with mBlock5 and USB cable if I am using admin accounts. But problem comes when our students try do this. They actually stuck on scanning the com port without anything show up. I have check the pull down list and sure that the software does not see the mBot Ranger.
However, I can see the com port being used for the connect even with the student account in the device management.
I have double checked everything and just cannot find the problem. Once I use an admin account everything go back to normal. Once I use a student account which definitely do not have admin permission, the problem happens.
Would anyone please kindly advice for the possible solution to this situation?
