Found the answer to this. I have to enable PM_SUSPEND in the kernel configuration to get the class files. But then, as mentioned in the comments, RaspberryPi has the power lines directly connected to the power rails
controlling hub power from linux shell

Pregunta
I am using a buildroot image (3.12 kernel) running on my raspberry Pi with a USB LED light connected to it and I want to control on/off through the CLI.
I went through this. However, there is no control or level file in the power folder.
Is there any kernel configuration that I have to enable to get this ?
