Hi,
you can get your username by logging into miningpuulhub and then navigating to the Edit Acount page.
Here you can see at the top of the page your username. This is for example mine:
and it will result in my config:
@echo OFF
REM Change the following address to your Zcash taddr.
SET ADDRESS=vertushi.bminer
SET USERNAME=%ADDRESS%.w
SET POOL=europe.equihash-hub.miningpoolhub.com:20575
SET SCHEME=stratum
:while1
bminer.exe -uri %SCHEME%://%USERNAME%@%POOL% -api 127.0.0.1:1880
#-nofee
timeout 10
goto :while1
However your username is most likely different;) so replace your username in the script with your username from the account page of mining pool hub and it should mine in your name.
