[avr-chat] Difficulty programming attiny13 with AVR dragon

[Kevin DuBois]

Hi All,
I'm trying to program an ATtiny13 with avrdude under linux (Ubuntu
10.10). I've determined that my hardware version is 7, and my firmware
version is 6.11.
It always fails, and I have not been able to program the fresh chip yet.

Here is the command I am running:
$ avrdude -c dragon_isp -p t13 -P usb -e -vvvvvvv

avrdude: Version 5.10, compiled on Jun 29 2010 at 03:44:14

         System wide configuration file is "/etc/avrdude.conf"
         User configuration file is "/home/kdub/.avrduderc"
         User configuration file does not exist or is not a regular
file, skipping

         Using Port                    : usb
         Using Programmer              : dragon_isp
avrdude: stk500v2_dragon_isp_open()
avrdude: usb_open(): cannot read serial number "error sending control
message: Connection timed out"
avrdude: usb_open(): cannot read product name "error sending control
message: Connection timed out"
avrdude: usbdev_open(): Found [unnamed product], serno: [unknown]
avrdude: usbdev_open(): error setting configuration 1: could not set
config 1: Connection timed out
avrdude: usbdev_open(): did not find any USB device "usb"


More details
* I've checked the wiring a few times, everything seems to be in order.
* There are no udev permissions problems, I've set up the rule
properly to give me access. The problem persists when I've run the
program as root.
* The LED status lights on the dragon are green (small LED), and
dark/off (larger LED), indicating a USB connection.


Can anyone help? I'm really at a loss for what to check next!

Cheers,
Kevin D.
