Is it possible to overclock the ASICMiner USB miners?  I know you can overclock the expensive one to 13GH/S, but what about the USB?

nope you cant overclock then.  The oscillator is a fixed one.

Are you sure about that? According to http://www.asicminer.co/about.html -
 "Generation 1: Block Eruptor. 130nm with 6-8J/GH. Each chip's rated frequency is 336MHz at 1.05V. It translates to 336MH/s because it does one hash per cycle. The chips work stable and well at 392MH/s at 1.15V. Further overclocking needs proper handling of heat and power supply."

Isn't the Block Eruptor their USB stick?
If so, it seems they could be overclocked by increasing voltage and good cooling.

He may know a bit or 2 about it...

I think these puppies will overclock fine with an innovative cooling solution.

From what I can tell, we'll need some type of software interface to make overclocking possible. 
I believe this was previously accomplished with GPUs through the use of OpenCL.  So we'd need info/etc from ASICMiner on how/if this is possible.

ck or kano can likely clarify.
No possible because the oscillator for the USB is a fixed frequency one. The voltage is also fixed at the lowest possible for the current frequency to match the 500mA spec of USB ports.

You can still try to lower a bit the timings on Cgminer, feeding more work over time. If it's successful you can increase a little the number of accepted works per minute!

Try --icarus-timing 3.0=90 on cgminer (but I haven't one so I can't tell)
