Try unplugging the stick for 30 seconds and then plug it back in. Do you have a USB tester?

No tester and I had tried unplugging for a moment hoping it might reset it then plugging it in to a different port and still nothing.

The support page includes how to properly test a CompacF miner when you have a working one and one that may or may not be working.

I'm having a similar problem and looking for advice.

I ran through Kano's support page mentioned above with no success. I was running the Gekko V2 hub which is working fine for my other sticks.

My Compac F seemed fine until it wasn't. I wasn't doing anything too crazy with it, and have the igloo style cooling fan which keeps it pretty chilly.

Now it shows up in cgminer with '0 chip found' or cycles through zombie mode until it's turned off. Both red and white lights appear if that helps.

I've been messing around trying to diagnose it. I do have a USB tester, and it's not really pulling any current through. I just pulled the heat sink to take a look at the chip and see if it heated up at all when plugged in. It doesn't have any visual signs of being popped, and didn't really feel like it was getting warm to the touch. With the heatsink off it would spike at about 1 amp (.4 with the sink on, no noticeable increase in temp) and did begin to heat up. I pulled the plug before it really got going.

Is there a common fail point with these other than the main chip? I saw a regulator mentioned before, is that a user replaceable component? I'm decent with a solder station, but SHOULD NOT be trusted to reblob chips.

Thanks.
