I am building a simple test rig for I2C controlled devices (LED drivers) that I can control from TouchOSC. The TouchOSC/WiFi/Bonjour and I2C parts are already working, but what I am wondering is whether I can safely disconnect a device from the I2C bus without having to power down the test rig.

Is it enough not to transmit anything while connecting/disconnecting, or is there a way to temporarily disable the I2C hardware on Teensy boards ?
