Something is fishy with your USB. > avrdude: usbdev_open(): Found [unnamed product], serno: [unknown] That alone should make you suspicious. For a correctly found Dragon, it should look like: avrdude: stk500v2_dragon_isp_open() avrdude: usbdev_open(): Found AVRDRAGON, serno: 00A200007BFE avrdude: usbdev_open(): using read endpoint 0x82 avrdude: jtagmkII_getsync() avrdude: jtagmkII_getsync(): Sending sign-on command: avrdude: jtagmkII_send(): sending 1 bytes (This is under FreeBSD, but that part of AVRDUDE is completely OS independant.) Make sure your lsusb command can find the Dragon correctly, including serial number and all that. AVRDUDE is at the mercy of your OS here. Check all the hardware stuff: cabling, USB hubs, hub power supply. Try connecting it directly to a host USB port. -- cheers, J"org .-.-. --... ...-- -.. .
