For Pickit 2, I was going by this list:

http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en027813

This says that most actually are.  I tried reinstalling my Pickit software
thinking I had an older verison, but it still gives me that same error.  No
device attached or no supported device.

Are there any common PCB board mistakes that I should search for?

I checked all the connections with a multimeter and they seem to all be
going to the right places.

Thanks again,
Adam
