Please reply to the list, not privately to me. If you can't see any devices, then it probably is permissions. If you are running as a user "tester" you need to give that user permission to access the /dev/bus/usb/*/* node(s). You can either manually change the permissions (which won't be kept across reboots/hotplugs) or you can edit the udev rule(s) which are probably at /etc/udev/rules.d/ to give permission to your user.
