This device is not able to make money for you at this point in the Bitcoin age.

I have not tested by how much the lifespan will increase but a 30 degree Celsius drop from 86 to 56 degrees would prolong any piece of electronics useful life. If you intend on getting one of these devices, adding a heatsync with some thermal paste will increase its lifespan drastically. 4 watts (a 20% decrease) most likely due to the temperature drop in the voltage regulator, increasing its efficiency and wasting less power in heat.

So i've changed it trying every driver with some of the miners.

WinUSB So i am, once again, reverted to CgMiner 3.4.1. Stratum from pool 0 requested work restart FAIL: USB remove not already in use (3:2) AMU 0 SendWork usb write err:(-7) LIBUSB_ERROR_TIMEOUT Unfortunately it still does not see USB devices: cgminer version 3.8.0 - Started: Ĭonnected to diff 1 with stratum as user joesmithīlock: 70bedfe6. This morning i tested CgMiner 3.8, hoping they fixed its inability to see USB Block Eruptors (and the stack overflow). So i reverted to 3.4.1, living with the semi-daily crashes and having to remember to restart CgMiner. Waiting for USB hotplug devices or press q to quit
