Absolutely the same problem here, Henrik. Did you make any progress?

Moreover, I find that all the USB bootloaders at Microchip, by default use a setting of HS Oscillator, PLL enabled, HS used by USB; with this I always get a USB Device Not Recognized; I have to change it to HS Oscillator, HS used by USB to get the pic (18F4455 in my case) to be recognised by the PC. But beyond this point, the loader fails to 'burn' the program in the pic; I have used the DEFINE LOADER_USED 1 and DEFINE RESET_ORG 1000h.

Wonder what I am doing wrong?

Incidentally, the test program works despite the 2 defines if I program it directly using a Pickit2. Didnt really expect that to happen?
