Hans, you have to check carefully if USB has indeed 48MHz clock. The jal package sample is supposing you are using 20Mhz crystal, there is PLL and correct divisor. If is not so, the USB will not work with the config parameters in the sample. Read first the USB operating theory and clock from datasheet and how to set your fusible for the right clock. Then blink a LED but with the clock intended for USB ( below) , not other sample. good luck!
