Hi
OC2000,
There is no driver for the Tubemeter. It is a standard USB HID device, so Windows already has all that it needs for it.
Did you connect it correctly? It is easy to make a mistake orientating the USB connector. If I remember correctly, Pin 1 of the Tubemeter should have the black wire connected and Pin 5 the red one. Pin 1 is marked. Check your Tubemeter manual to make sure.
Kind regards,
Boris Cikota.
