I’ve installed all of the software with the GHI executable, but when I plug the USB into my laptop, it’s not detected. How can I trouble shoot this? Shouldn’t I be able to see it in the USB list in the device manager?
Are LEDs lit on the power module and on mainboard?
Yes. Shining brightly on both.
So I reseated the cable and all is well. Sorry to bother.
Did you change the configuration switches from default?
Can you try a different USB cable? Different USB port? Different pc?
Oh you got it 
good
Wellcome to the community btw
Had similar problems. Was going into a powered hub. Tried a port on the back of the desktop, worked better.
If I wanted to use the power connector on the USB client board, what should I plug into it?
For the USB Client DP, looking at the bottom it reads: “7 to 30 V” - with + and -, so DC - any wall wart that puts out between 7 and 30 volts DC should suffice. I’m using one from an external USB drive that has a compatible power plug - I haven’t gone crawling under my desk to check out the exact specs, but it works.
Correct and the plug is 2.1mm
I’ve since found that using a powered hub with no other devices seems to work, so i don’t have to squat on the floor next to my desktop computer.
