thanks Kano, I thought I tracked it to cgminer, but was a prob in my own code :-) Great soft!
I've got a problem with API command addpool. It looks like it always forces username to lowercase. It looks neat, however when using P2P pools and using bitcoin address as a username this is quite a problem.
Version I'm using is cgminer 4.1.0 (embedded in Terraminer IV). I do not really dare to try to fix this on my own and recompile as it might be tricky to compile for their embedded linux.
Are there any workarounds?
No it doesn't.
(also note that whatever Terraminer does to cause this, we don't in cgminer)
