Good point, I should have considered that. Maybe I was really thinking 
of SELinux. But it's disabled on this machine. Silly of me.

OK, I follow you (and am learning from you too.)

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.

I'm not sure what you mean here by 'USB to serial device with TTL level 
outputs'. Yes, the programmer is plugged into a USB port on my FC5 
machine at one end and an Atmel-based controller board on the other end. 
I want to program an Atmel Atmega128 chip which is on the controller 
board. It has a Maxim Max3222 chip on board. The board is intended to be 
a robot controller.

There is only /dev/ttyUSB0.

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

Thanks!
