Which means you still need to answer post #11
Ahh. I see. Ok. Well. I actually switched to a 4mhz resonator, just to confirm that it is 'near working', i tried it with the 20mhz one and the pc didnt recognize it, so at least the code seems to be attempting a usb connection. I have turned my suspicions on the cable. Ive got the colors right, but when I try to test them to the usb cable pins as they are listed at (http://www.usbman.com/Guides/BelkinM...e_assembly.htm) using a multimeter, they are all different. Interestingly, connecting the USB power lines into the power bus of my pic proto board powers it fine, i tried it with a non-usb led blinky and it powered it, so i still think the cable is OK...

Grrr. First timing USB is hard!

i will check the config conflict issues and see if i can get it to compile
