FAIL: USB get_lock not found <1:1

I'm starting to have trouble with my Gridseed again. Scrypt only seems to work fine. However, when I try to use cgminer for SHA256 only it seems to start up fine for a moment and then shows the message "FAIL: USB get-lock not found <1:1>". Can this be fixed? I'm a little worried this is a physical problem because my gridseed seems to be causing RF interference for the AM radio across the room that hasn't been there when running the gridseed scrypt only mode in the past.

Now it seems to show hashing but 0.0 WU/m.
