Reconnect top-block

Hello,

I am trying to change some of the configurations dynamically in
tunnel.py,
e. g. modulation and bit rate.
I tried that by doing a lock in the tunnel.py-file:

self.lock()
self.disconnect_all()
self.txpath.reconfigure(mod_class, options)

self.connect(self.txpath);

self.unlock()

and as well in the transmit_path.py-file:

    self.lock()

self.disconnect_all()

When reconfiguring in transmit_path.py I get to the point:

    self.u = usrp.sink_c(fusb_block_size=self._fusb_block_size,
                         fusb_nblocks=self._fusb_nblocks)

There the call gets stuck and I receive error messages:

     usrp_open_interface:usb_claim_interface: failed interface 2
     could not claim interface 2: Device or resource busy
     ...
     in _setup_usrp_source fusb_nblocks=self._fusb_nblocks)

Since self.u is used for the reconfiguration I tried to reinitialize
this.
Could anyone give me an advice how to reconfigure self.u?

Thanks a lot.
