Hi,
I am posting this to share my experience with the new Pixy CMUcam5.
I was very exciting when it first arrived. As usual, I plugged my Pixy to the Windows 7 computer to see what come up after install the software. No thing, even a warning message.
After browsing various forums, webs, … I see people have the same problem, and most of the time is it the bad USB cable.
I have tried 3 of them, knowing that they are good USB cables, even on a Mac !!! Still no luck.
Next I checked the voltage With the multimeter, there is no 3.3V at VCC !! Just 0.3V, a resistance check between any capacitors shows a short circuit between 3.3V and GND. Strange!!
After a close-up check, I notice the capacitor C40 (near USB port) is flipped side way ! Properly because of some impact when shipping/packaging. Then I just took it out, and even more strange the capacitor C40 is short-circuit by itself. That lucky, because the board now has VCC 3.3V and it is recognized by the computer !!!
I am not sure what the role of the capacitor C40 and how it is become short-circuit (and the board is still working without it). So I am passing this message to the people in case of you have the same problem, and to the developers if they can prevent this happen again.
Cheers.
