Today I finished building the board en tried to connect it to een Win7 PC.
First I connected the 12V, the power LED becomes solid red.
Then I connected the USB cable, at the PC wouldn't recognize the device, so I installed the driver as mentioned in the tutorial "Using the configuration utility".
It installed the driver, but the device manager reports an exclamation for the "AstroEQ mount Controller (COM3)."
Switching off the power and removing the USB connection for ten seconds and trying again has no result.
Once the USB LED was flasing, then I tried to run the configuration utility and uploaded the firmware, but still the computer won't reconize it. I can choose COM1 and COM4, but not COM3 and that where the device manager says the controller is.
Looking at the controller at the moment, POWER and STATUS are lid, USB flashes and I cannot find the meaning of the LEDs.
Please help.
