This is a bit off topic from where this thread is going, but I need a little help if anyone can provide it. I have 2 k16s, fully assembled and visually everything checks out, but neither one is recognized when the USB is plugged in. No blinking LEDs, just buzzing caps.
If anyone would mind helping me out, I'd have no problem tipping what I can or test these via your pool/address of choice.

it sounds like you might have a short somewhere in the power supply output. Did you measure voltages with a multimeter? Do you have an oscilloscope?


I tried 2 different power supplies, one that I set up just for the k16s, and the other supplying my BE blades. Both are putting out a solid 12v. As for probing the board itself, I'm not sure where on the board is good to test with. Unfortunately, I do not have an o-scope. I've always heard that buzzing caps were normal, although they may have been shorted now that I think about it. It's possible that my heatsink shorted the PCI-e power pins. I noticed there wasn't enough of a gap to feel comfortable with, after I tested them. You think it might just be the caps?

Edit: Also, do we have an IRC channel?
