Hi. Need help here. I followed everything here.....https://litecointalk.org/index.php?topic=7722.0 (Guide on how to mine litecoins).
Used the CGMiner version but when I started cgminer 3.5.0 I kept on getting these:

c1DevicesNum returned error, no GPUs usable
No devices detected!
Waiting for USB hotplug devices or press q to quit
Probing for an alive pool
Pool 0 difficulty changed to 256
Network diff set to 338M

These are the specifications of the machine im using. I have no idea if this is capable of mining litecoin.
