I need help to fix this error I am getting on my Raspberry Pi 2 B+ model with my Antminer U3's connected, i am running cgminer 4.9.0..
The setup is working great for about 6-12 hours then I get an error message on the screen... Its always the same error message..

Code:

AMU1: Comms error (werr=0 amt=32)
AMU2: Comms error (werr=0 amt=32)
AMU0: Comms error (werr=0 amt=32)
AMU 2 SendWork usb write err:(-7) LIBUSB_ERROR_TIMEOUT
AMU1: Comms error (werr=0 amt=32)
AMU2: Comms error (werr=0 amt=32)
AMU 2 attempted reset got err:(0) LIBUSB_SUCCESS
AMU0: Comms error (werr=0 amt=32)

Can someone please help me get rid of this error, It would be nice if I could leave my miners alone for more than 12 hours...

I had the same problem with my zeus blizards, what fixed it for me was turning the clock speed down a little.
