If I'm reading your script correctly, you are essentially starting:
owfs -u
owserver -u -p 3001
owhttpd -s 3001
If so, the first program to grab the USB port (probably owfs) will block the
second (owserver).
Instead:
owserver -u -p 3001
owfs -s 3001
owhttpd -s 3001
So owserver is the only program to directly connect to the USB bus master.

Start uncovering the many advantages of virtual appliances
and start using them to simplify application deployment and
accelerate your shift to cloud computing.
