Can anyone help me? i'm at my wits end 
My nanofury works perfectly through the laptop USB port but when plugged into my usb hub (plugable 4 amp power supply) it runs for 5-10 minutes then just gives this over and over. Normally straight into the laptop I use this and it runs fine with a usb fan on it, i just get the odd frequency drop line popping up.
I have dropped it down to
Through my usb hub and still getting the problems what would cause this?

Mike - try this: Press [M] to go to the device manager, select the device in question, press
- to change the oscillator bits, put some very low number - like 20 or 30 and hit enter. That should reinitialize the device. Give it a few seconds and see if those messages stop. You should see the device coming back up and hashing (at some low speed). Once that happens go back in and change the bits to the high number you used before.
What I suspect is happening is the miner overheats. Try a bit lower speed than 54 - like 53 or 52, or try pointing a fan to it.
If you have an infrared thermometer check the temperature - if you see it going over 85C you're exceeding the limits of the components.
