Thanks, Dave and Henrik. Yes, I am using a 18F2550_4550, and I missed that in the Data sheet. Since my PCB is already designed for the 28 pin 18F2550, I guess my only recourse now is to find a 28 pin chip counterpart to the 18F2550 that doesn't have USB that will let me use the RC4 and RC5 pins as outputs. Thanks so much for setting me straight on this....I have been troubleshooting this for 5 days and never thought to check out the multiplexing of the RC4/RC5 pins.
