Hello, newbie here and I'm also a newbie miner.
I just got a R909 and today I've been trying to connect it to Nicehash, which worked but xnsub is not supported.
The customer service told me to enable extranonce using the code "stratum+tcp://sha256.auto.nicehash.com:9200#xnsub", however, it did not work.
I wonder if there is any tweak that can make it work? Many thanks!
Did you tried with this fork of cgminer ?
