Make sure your crystal matches your compiler settings. Make sure your fuse settings have the external crystal configured.

I would like to create device with vusb but I what to supply it from external 5V source. I have "unrecognized usb device". Please look at this fragment of my schema. After 2k2 resistor I have 5V. Atmega work good with ISP programming - only vusb part not work. I think my configuration in usbconfig is ok (PORT D nr 0 and 2). I check my board with hid-mouse example (previous board with usb supply from 1 leg on usb worked ok). Sorry for poor english.
