Re: Where Is The AVRISP USB Programmer When I Plug It In?

First, thanks a lot for taking the time to make your suggestions. I really appreciate it.
  Stopping IPtables is not going to help. This is not a network
problem. IPtables will only affect a USB NIC, and not other USB
devices on the local machine.
Good point, I should have considered that. Maybe I was really thinking of SELinux. But it's disabled on this machine. Silly of me.

If the problem were that the program could not write to the serial
port, you should see that is the dialog from avrdude. It looks like
the program is able to read and write the port.
OK, I follow you (and am learning from you too.)

Now, I have a couple of questions:
Does the programmer plug directly into the USB bus, or is the a USB
to serial adapter that is then plugged into a serial port on the
programmer?
It plugs straight into a USB port. Has the usual 'A' style USB connector. There is no USB-to-serial adapter although I have one still in the clamshell packaging. If you want I can send you a photo of the programmer off-list.

This is typical of many devices, I wrote a device driver to talk
to a few and I cheat and treat them some-what like a serial port
(I'm missing a lot of termio support which causes some problem
with some software).

Do you have any other USB serial devices? (ls /dev/ttyUSB*) If so,
are you sure you are using the correct one?
There is only /dev/ttyUSB0.
Are you sure the programmer works?

No, I'm not sure. I'm going to test it on a different computer tonight.

If the is no /dev/ttyUSB0 (ls -l) /dev/ttyUSB0, check /dev/usb/ttyUSB0
if it is there check it's permissions. I got the impression the usb
sub system created the device. Still might be a permission problem
(kind of doubt it though).

What software (name) and hardware (name)?
