Just as a heads up, the only way I was able to get cgminer to see my BlueFury under Mac OS 10.7, 10.8 and 10.9 was to 'unload' the new USB modem
sudo kextunload -b com.apple.driver.AppleUSBCDC
sudo kextunload -b com.apple.driver.AppleUSBCDCACMData
Hopefully this will save someone else a LOT of hair pulling
Finally have a BF1 (Red Fury on-loan) and can confirm this. Before doing this I would get the following error:
cgminer -d?
[2013-11-21 15:06:02] Started cgminer 3.8.2
[2013-11-21 15:06:03] bitfury detect (93:2) failed to initialise (incorrect device?)
[2013-11-21 15:06:04] Devices detected:

After unloading both kernel extensions and re-plugging the device cgminer was able to recognize it.
