The wire library does not work in Intel Galileo IIRC...
Are you powering the module with 3.3 or 5v? About
There is a LED indicator on the sensor so it is getting power fine.
Take into account that a LED usually indicates "some" power, not necessarilly enough for the module. I've used a HC-05 and it failed with 3.3v even when the LED was on.

Some time ago another user reported issues with this sensor when using it with Galileo. As you can see in this thread: https://communities.intel.com/message/222253#222253, it's a speed issue with the Galileo's I/Os. The sketch seems to be fine, however the issue is not at software level but at hardware level.
You can also try to upload the sketch attached below (I2CScanDevices) just to check if your device is at least recognized by the board. If it's recognized, then the issue could be related to the example code or the library used and it might be fixed, but if the device is not recognized, I'm afraid the issue is because of the Galileo's I/O.
Hope you find this information useful.
