[C.CC USERS] Almost there with Ubuntu

[Dennis Meade]

Hi, Guys

Now that I have the hardware, switching to Ubuntu under VirtualBox is so 
much easier. My only problem is with USB connections about which I 
haven't a clue with this setup. The documentation I've found hasn't 
helped at all.

I've run the build for the firmware:

/build.sh --with-target-board=arduino --with-upload-port=/dev/ttyUSB0

That ran OK, but "make upload" fails with the following.

avr-objcopy -O ihex -R .eeprom tvm-arduino tvm-arduino.hex
./reset-arduino /dev/ttyUSB0
Traceback (most recent call last):
   File "./reset-arduino", line 7, in <module>
     ser = serial.Serial(sys.argv[1], 57600)
   File "/usr/lib/python2.6/dist-packages/serial/serialutil.py", line 
166, in __init__
     self.open()
   File "/usr/lib/python2.6/dist-packages/serial/serialposix.py", line 
175, in open
     raise SerialException("could not open port %s: %s" % (self._port, msg))
serial.serialutil.SerialException: could not open port /dev/ttyUSB0: 
[Errno 2] No such file or directory: '/dev/ttyUSB0'
make: *** [upload] Error 1

lsusb reveals:

Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

In the Windows Device Manager everything looks ok with the USB port 
masquerading as COM3.

Any ideas?  I found something about permissions. but that does not seem 
to be the problem or maybe that's causing the "no such file or directory".

Regards,

Dennis
