Sorry Noob question.
When i try to run cgminer 4.7.0

cgminer.exe -o stratum+tcp://stratum.pxc.theblocksfactory.com:3332 -u user.worker -p x

"No devices detected"
"waiting for usb hotplug device..." 
"Probing for an alive pool"
"Network diff set at 0"
"Stratum from pool 0 detected new block"
"
"
"

Do i need to specifiy what device in login command?
I am only running CPU and Nvidia card.  Trying to mine with CPU, since vid card was only purchased for video playback.

Okay I just tried with a different pool.  blocks still not accepted

Am i loggin in wrong?

minerd.exe -o stratum+tcp://stratum.pxc.theblocksfactory.com:3332 -u username.worker -p password



If I use Phoenixcoin to mine with:

minerd -a neoscrypt -s 48 -o stratum+tcp://stratum.pxc.theblocksfactory.com:3332 -O username.worker:password -t 1 -r -1 -P

Same result

non of my blocks are being accepted.  over 150 blocks now.  I am a noob.  Am I doing something wrong?
Same result with a Win7-PC and RaspberryPI both using Minerd

I am mining with cpuminer on a raspberry pi as well at a windows pc.
Both keep showing NOT ACCEPTED.
