I am trying to building one of these barebones http://chipkit.net/diy-chipkit-board/ But I can't get the USB/Serial drivers installed correct. I have tried whith these drivers: http://www.chipkit.org/forum/viewtopic.php?f=20&t=2289&p=8597&hilit=usb+driver#p8597

I have also tried the drivers that comes with the download of the IDE But I keep getting the message "Cannot start device code(10) when I look at the port in device manager.

I have tried both Windows Vista and Windows 7.

Any solutions/suggestions ?

Is the device mentioned in Device Manager? What VID and PID is it reporting?

Thanks for answering

Yes it is reported in Device Manager, but with a yellow warning.

It is reported as vid_0403&pid_a662

Apparently error 10 is a generic "Something didn't work, but I don't know what" message.

My best guess is that maybe the clock isn't quite running at the right frequency - possibly you have the wrong capacitors for your crystal (the 36pF ones quoted there are specific to the crystal they have - check the load capacitance for your crystal), or maybe the breadboard is adding extra capacitance (breadboards are notorious for that). Also check all your voltages - make sure they are as close to 3.33V as possible (except Vcap which should be less).

Thanks Majenko,

I got it working, it was a stupid mistake by myself, I had the D+ and D- wires swapped :oops:

I use 22pF caps on the x-tal (just as my breadbooard Arduino's)

And finally I decided to move the whole thing to a Strip-board, I had to many problems with loose connections on my breadboard.
