Hi Bob,

 From your ls -la printout it looks like the ports can only be opened by root. Did 
you do the sudo chmod 666 /dev/ttyUSB0 and sudo chmod 666 /dev/ttyUSB1 commands?

This is what you should see after doing them:

crw-rw-rw- 1 root dialout 4, 64 Jul 19 17:52 /dev/ttyS0
crw-rw-rw- 1 root dialout 4, 65 Dec 31  2009 /dev/ttyS1

Note the extra rw in the permission information.

Regards,
-Larry
