My Go Direct SpectroVis Plus is not identified.

USB Connection

NOTE: If you are collecting data via USB, you do NOT need the battery installed or the AC power cable connected. Removing both of these will likely solve most issues.

Unplug and replug the USB cable.
Switch the USB cable with one that you know works.
Switch to a shorter USB cable.
Do not use any adapters on the USB cables.
Use a powered USB hub between the spectrometer and the computer or LabQuest, if possible.
If you are on a LabQuest unit, completely reboot the LabQuest
- Original LabQuest⚊Home > Control Panel > Reboot
- LabQuest 2⚊Home > System > Reboot
- LabQuest 3⚊Choose Reboot from the Settings screen
Unplug the spectrometer from all cables. Press and hold the power button until the LEDs go off and try reconnecting.
With all cables disconnected and the spectrometer powered down, attach the AC power cable that came with the unit and then plug the USB cable into your platform.

Bluetooth Connections

See Why can't my device find Go Direct Spectrometer when I try to connect via Bluetooth?
NOTE: LabQuest is not compatible with Go Direct Spectrometers via BLE. You must connect via USB when using LabQuest 2 or 3 for data collection from a spectrometer.

If none of these fix the issue or you have to do this repeatedly with the same spectrometer, Please contact Vernier Technical Support. Please include the serial number of the unit.
