Maybe running in verbose mode might give some idea of where it's failing. Do you see your device when you rub usbconfig?

Usbconfig dump_device_desc will show you the details of your device. If they do match I’m not sure where you would go from there without debugging the code but I think the permissions of your serial devices is a red herring. Andrewhelp
