I just got a guru plug server, and would like to do some zigbee/zwave development. 
I followed these instructions, and there is no ttyUSB0 device, or any kind. 
I could have ordered the wrong thing, but didn't know what I was ordering. 
My question is how do I get zwave and zigbee on my device? 
Also, where is the documentation for developing for these devices.
