Bad news... I popped it 
I had it working with a 20 mhz crystal for 5 minutes still was testing the hash rate... then it stopped responding. Now cgminer cant identify it, even with the stock resistors and crystal in place
I felt so bad, why I didn't post anything in a while.
On another note I figured out my clock gen circuit was putting out 5v not the 3.3 it should have been. Chances are this is what killed the chip not the speed.
still though I popped it
Got 3 more coming in the mail soon
I wonder if I could get a replacement chip cheep?

yes, i think for your work we all should spend you another usb asic miner for your (our) tests you make!
if it is not detected, then i think it have nothing todo with the asic itself...
cause it should be detected even without the asic soldered on board.
the silabs usb to com emulator should handle it... i only know use ftdi in my flasher box, but i think its works the same way.
