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.

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 think not, because Windows computer works fine with BitMinter client and powered hub, but here are specifiations of my hub: Power supply 5 W Input voltage 100 - 240 V Output voltage 5 V Input frequency 50 / 60 Hz Output current 1 A //definetely not. Now i tried with one Block Erupter connected to HUB and one connected directly to computer, and effect was same, so i am sure there isn´t problem with power

Make sure there isn't another libusb-1.0.dll somewhere on your system?

Ah wait you're on linux? Here I was talking DLLs Grab Kano's binary which has the other libusb built in statically. The problem is the old libusb is broken on both linux and windows. Here. I even went to the trouble of finding the relevant post: https://bitcointalk.org/index.php?topic=28402.msg2983720#msg2983720

I think not, Output voltage 5 V Output current 1 A 500mA + 500mA = 1A. Not counting the hub's overhead, so your hub's PSU is underpowered.

It's actually a binary file, the "a" is just part of the version number. No compiling necessary. Open a terminal and type in these two commands: wget https://github.com/kanoi/cgminer-binaries/raw/master/Ubuntu_11.04_x86_64/cgminer-3.4.0a chmod +x cgminer-3.4.0a Then run cgminer like you normally do (you can even rename 'cgminer-3.4.0a' to just plain 'cgminer').

Knock yourself out chasing your tail. Indeed, a Block Erupter needs 505 - 510 mA, a USB 2.0 Port only delivers 500mA, so this cant work from a USB 2.0 port directly. You can either plug them into USB 3.0 ports (which deliver 1000mA per port) or use an USB hub with enough power.

They might work with not enough curent, but the they are runnng slower thann 336 MH/s. Maybe somethings there is wrong with your hub? //btw my last message was:

-bash: ./cgminer: binary file cannot be executed
i replace old cgminer file
change rights with chmod. start bash and then go to the directory that contains cgminer. Then do (lower right might do as well, but 777 is easy to remind)
