They are on a powered Generic Stables Hub at the moment. I have tried it on all ports though. 2x(usb3) 6xUSB2 on back and 2xUSB2 on front.

No Devices found.


UPDATE!!! I was playing around with windows tools and setting a Reg key for the driver myself instead of letting Zadig do it for me. THE LIGHT TURNED ON!!!

Not sure if its good or bad, 4 blinks then solid light.

I still cannot get either miner to pick up the erupter but i am at least happy to see the light come on finally.

No Devices detected.

I have tried every version of CGminer, 3.1.1, 3.1.4, 3.4.1, and 3.8.3 always the same No devices detected. The light has only ever come on 1 time and it still never picked up. If I remove the driver all together and plug it back in the light flashes really fast then nothing.

My computer picks the stick up and auto installs the Slabs driver. I then use Zadig to replace the driver. If I do not replace the driver CG miner gives me an error saying to read the read me file and update the driver. When I update the driver with Zadig the error goes away but still never picks up a device. BFG is not picking it up either.

Previous owner says the stick was working when he shipped it to be but more and more im starting to think the stick is a dud. I have tried every command line I can find on the forums, with icarus and without. the only command i was never able to get to work was the -S all command.

Using an ASIC erupter with this line C:\cgminer-3.4.1-windows\cgminer-nogpu.exe -o stratum.bitcoin.cz:3333 -u xxxxxxx -p xxxxxxx --icarus-options 115200:1:1 --icarus-timing 2.6316=100

No devices deteteded. Used Zadig tool for driver, cannot get bfg or cgminer to pick up erupter.

Yes, i have run the zadig tool and it does correct the error for CG miner, I can also load the standard drivers and have BFG pick it up. I have watched CGminer change when I change the drivers...i e gives me an error then I change the driver and I do not get the error any longer.

My computer seems to be picking up the erupter without issue and allows me to re-assign the drivers just fine. I just cant get BGC or CG miner to pick up.

I am also using a command target with icarus timing, everything loads and logs into pool just fine. BFG will pick up my CPU but never picks up the erupter. CG miner never picks up the miner.

I am aware there are most likely dozens of posts on this as I have been reading them over for the past day and a half.

I am new to the forum so I must post here first, sorry for asking a question that has been asked before most likely.


I have acquired a new USB erupter and I am having problems getting both BFG and CG miner to pick it up. I have been GUI mining for a few weeks and have accumulated a few dollars worth of bitcoin so my wallet and understanding of the system is not a problem.

I beleive i have correctly compiled a windows 32 cgminer with mingw but I am still getting the no devices detected prompt when loading cgminer. I get a connection to my pool and login just fine but CGminer never picks up the USB miner.

I have also corrected the driver problem with zadig, that was my first issue.

Again, I have been over many many forums and read through the read me files in cgminer.

Any responses are appreciated, even if they are just to recheck all of the steps involved. I am not great with a compiler and some of the steps may not have come out correctly but when I run the cgminer folder that I put together CGminer does load normally just does not find any devices.
