Fred:

	Do you have permission to access the port??

When first created, mine showed up with permissions:

HAWKSoft(chrish)$ ls -l /dev/ttyUSB0
crw-rw---- 1 root uucp 188, 0 2009-01-03 17:07 /dev/ttyUSB0
(usable by root and owner uucp)

I had to change it to:

crw-rw-rw- 1 root uucp 188, 0 2009-01-03 17:07 /dev/ttyUSB0
(usable by root, owner uucp, and everyone)

Then I could use it.
