Who is the owner of /dev/ttyUSB0? Is it lp?
Perhaps the first thing to try is to uninstall cupsd, do you want to do that? It may not be worth it. But since cupsd is taking over ttyUSB0, removing it to check might help. Or perhaps you kill -9 9672? Or whatever is the process during a particular boot that grabs /dev/ttyUSB0? Ideally chown .... /dev/ttyUSB0 and chown ... /dev/ttyUSB1 should also help. Along with that, you'd have to do chmod too. Here's the output for my config: m...@ubu:~$ ls -l /dev/ttyU* crw-r--r-- 1 root root 188, 0 2009-03-29 16:51 /dev/ttyUSB0 crw-r--r-- 1 root root 188, 1 2009-03-29 16:51 /dev/ttyUSB1 I am still reading about this problem, will let you know if I find something.
