[avr-chat] Need help with Avrdude and Arduino Uno

[John Tucker]

All:
Just getting started with Arduino Uno. Received board recently after
wrestling with getting toolchain compiled and now having problems
with Avrdude.

I'm using Knoppix 6.4 and averdude 5.10:
<input>
address@hidden:/home/knoppix# ./avrdude -c avrisp2 -p m328p -v

<output>
avrdude: Version 5.10, compiled on May 24 2011 at 21:10:31

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

         Using Port                    : /dev/ttyS0
         Using Programmer       : avrisp2
avrdude: stk500_2_ReceiveMessage(): timeout

dmesg shows following relevant info:

If I use find to search for ACM and later for Arduino:
<input>
find /dev -name "*ACM*"
<output>
/dev/ttyACM0
/dev/.udev/db/tty:ttyACM0

<input>
find /dev -iname "*arduino*"
<output>
/dev/serial/by-id/usb-Arduino__www.arduino.cc__Arduino_Uno_64932343838351D082C0-if00
/dev/.udev/links/serial\x2fby-id\x2fusb-Arduino__www.arduino.cc__Arduino_Uno_64932343838351D082C0-if00

~~~~~~~~~~~~~~
Somewhere in my searching I think that I saw that an ACM1 should also 
have been created in /dev? Is that the problem and if so why has it 
not happened?

This seems to be some kind of [hard|firm]ware problem to me but I'm
stuck. Anyone that can help?
