You at least need to open a command prompt and run the command and see what the error is.
More details if you add -D --verbose to the cgminer options.
But most likely it will show without them.
Also ... cgminer -n will tell you what hardware it finds.
like: cgminer.exe -D --verbose --bmsc-options 115200:0.57 -o stratum+tcp://hashgoal.com:3332 -u 2XdsyV7ThMVPp65PxSmWmjpoL1ctW1rJDk -p x --bmsc-voltage 0800 --bmsc-freq 1286
?
because of i do this, i get nothing to see.
That's not cgminer.
There never has been and never will be --bmsc options in cgminer.
It's some manufacturers version you were running before.
If you ran it on the command line it will tell you that there's a problem with your options.
Something like:
[2015-06-07 13:06:24] ./cgminer: --bmsc-options: unrecognized optionWith the official master cgminer 4.9.1 you most probably want to be using the icarus driver options if that is a bitmain U1/U2/U3
However, as with all of our drivers we write, you don't have to supply any device options to make them work in default settings.
For the U3, the options (if you wish to change the default working options) are
--au3-freq,
--au3-volt and
--icarus-optionsSee the ASIC-README
