Topic: Low speed at two Block Erupters (CGMiner) :( - page 2. (Read 4310 times)
maybe its a bit underpowered? I had a similar problem when I connected two Block Erupters to a 5-port USB hub with cardreader that only has a 1000mA PSU.
I upgraded to latest version. But nothing changed

Upgrade to latest version of cgminer and reboot to make sure it uses the included DLL for the usb library. Older DLLs had this problem.
Hello,
today arrived second USB Block Erupter, so i connected it to my Debian linux server. But its slower than mining with only one !
Here is output:
I tried it on Windows computer with BitMinter client and it works normally at speed of 655Mh/s
P.S. I am using powered USB HUB, because Windows computer can´t handle 2 Block Erupters
