USB2 port LED flickering very fast.

[Corvl]

Good evening!

Recently I build a serial gateway with an arduino nano to controll a servo via another nano.
This worked well.

Today I wanted remotely ( I was far away from home) to controll this servo and I noticed that my vera3 was not responding.

I just came home and noticed that USB2 led was flashing/flickering very fast. I unplugged the vera 3 and plugged it in again , I had to setup the serial port again, and all worked fine.

But the USB2 port is still flashing very fast , maybe something like 10 times a second. I don't recall vera doing this before.

Someone has an idea what went/is wrong? and how to troubleshoot?

thanks,
Cor
