In order to connect USB devices to an app running in a browser, you must manually set up the connection. It is possible to set the browser permissions so that the app will not ask to connect to a USB device. When this happens, the app does not respond to device type selections, such as Go Direct USB or LabQuest.
Vernier devices fall under two categories, HID and USB.
- HID devices: Go Direct Sensor (USB), Go!Link, Go!Temp, Go!Motion, Spectrometers, Mini-GC.
- USB devices: All LabQuest devices and interfaces (LabQuest Mini, LabQuest Stream, LabQuest 3, LabQuest 2, Original LabQuest)
