Hi robert,
Accessing USB ports on a Linux machine may require root level
access. You are not logged in as root. You may be able to
proceed if you have used 'chmod' to change the access mode
of the appropriate devices in /dev/bus/usb. That requires
root access also. We'll continue, but if you don't see your
LDA devices or no data can be read from or written to them,
that's probably the problem. su to root and try again.

Try running with 'sudo', or become root by running 'su' before.

You can use udev rules to allow access to USB devices by user processes.
