One thing I will note is that there is a defect with the indicator light in the 1.01 firmware for the RE7. Aeotec released 1.02 about a week ago or so, which fixes the defect.
You don't need a driver for the device to function. However if you want to control the light, there are a couple of drivers around. If you are okay enrolling the device insecurely, I have one here:
@bcopeland also has one that presents the indicator as if it were a switched light. You can find it here:
I don't know whether Bryan's works with secure enrollment or not. However if anyone's would, it would be his.
