Error "uvc_open: Not supported (-12)" with libuvc for RICOH THETA

I’m trying to use libuvc for RICOH THETA, which is just released.

I’ve updated the firmware for THETA V to the latest one(3.40.1).
I successfully built the library and the sample program on both two Ubuntu 18.04.4 LTS environments: Jetson TX2 and a Generic PC.
However, sample programs dont work with the error “uvc_open: Not supported (-12)” on both environments.
Is there anyone who faces the same issue?
