Can you change the code so that it preserves the current overclock setting for 'new' Antminer U1 devices.   When I have to unplug and re-plug the mining hardware the Silicon Labs driver on my MacBook Pro assigns all the Antminers and Block Erupters new device names.  Version 1.5.0beta2 changes the 'new' Antminers to 1.6 GH/s.

Is there a way to fetch the current setting from each Antminer U1 and use that?  It's a pain to have to re-set all five, especially since only one can run at 2.1 GH/s. Especially since I can't seem to get the "Identify" buttons to work (the red LEDs don't blink and the 'share found' green LEDs blink all the time).

The Tune & Tweak UI is very slow on my MacBook.  It often takes several seconds to respond to a mouse click.
