By changing out the 12 MHz crystal connected to the ASIC and fiddling with the voltage with a trim pot, was able to overclock the ASIC core from 336 MHz to 560 MHz. Inside, he found a custom ASIC chip, an ATTIny2313, a USB UART converter, and a voltage regulator for the ASIC. begins his tutorial with a teardown of the Block Erupter hardware. This speed isn’t enough for some people, like who overclocked his Block Erupter to nearly twice the speed. Now, hardcore miners are moving on to custom ASIC chips like the Block Erupter, For around $100 USD, you too can mine Bitcoins at 300 MH/s with 2.5 Watts of power and a single USB port. Three are using the libusb-win32 driver, three are using the driver, and the rest are using the Silicon Labs CP210x USB to UART Bridge driver:īoth CgMiner and BfgMiner detect no devices.The name of the game in mining Bitcoins isn’t CPUs, GPUs, or even FPGAs.

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

Accepted 487047eb Diff 3/3 AMU 3īut it regularly crashes with a stack overflow.Ībout a month ago i tried to upgrade to CgMiner 3.6, but it fails to find my USB devices: cgminer version 3.6.0 - Started: It can see my four USB Block Erupters, and works: cgminer version 3.4.1 - Started: I've been using CgMiner 3.4.1 since late September.
