Thanks for the advice, I do have a 20Mhz Xtal and 20pf caps for it, It's set up just like the 4Mhz, as far as the hardware side goes. Is the PLL only for the USB, or does it speed up the Pic's code execuition also? I keep reading myself in circles in the data sheet trying to figure that one out. Should the OSCCON settings be removed?
I'll try the configuration from circuitpro's post.
Thanks,
