Try this:

In the F10 Gnome desktop
System Menu->System->Authorizations

In the Authorizations gui tree select

org->freedesktop->hal->device access->serial modems


Change the authorizations to whatever you like. You can open to all
users you can open to just the active console user, you can select
users.  For the sake of testing open it up to anyone without needing
authentication. Once that is modified try plugging in the usb serial
device and seeing if access works for your user.
