So the device is connected? That wasn't clear from your first post.
The device is hooked up to the SDA and SCL through pull up resistors.
Through? The pull-ups go to 3V3 and the device should directly connect to SDA/SCL.
Please provide a wiring diagram.
Remove the delayMicroseconds(), the bus doesn't have to settle. But you should read the return values of Wire.endTransmission() and Wire.requestFrom() because they'd tell you if the request was successful (ACK or NAK received).
