Had a very stable Rasperry Pi setup with a D-Link DUB-H7 powered hub and 4 block erupters. I have now switched to 1 antminer U1 and can't make 24 hours without a lockup of the Pi.
Here is my string: sudo ./cgminer/cgminer --bmsc-options 115200:20 -o www.url.com:port -u username -p password -bmsc-freq 0781
CGMiner is the friggered 3.8.5 version
Any help is appreciated.
