Hello,

I have an Antminer U3 connected to my laptop via USB. I have setup a .bat file to run cgminer.

I have the following in the .bat file:

cgminer.exe --bmsc-options 115200:0.54 -o stratum.bitcoin.cz:3333 -u dwyer17.worker1 -p 1234 --bmsc-voltage 0800 --bmsc-freq 0982

When I open the .bat file, cgminer says:

"No servers were found that could be used to get work from."
"Most likely you have input the wrong URL, forgotten to add a port, or have not set up workers"

I can't connect to Slush's Pool!

Please help me out.
