*DEPENDS* - what is needed to build it
R*DEPENDS* - what is needed to use it R-> runtime

usbctl is used to control the power of the specified port. But usbctl
works only with sharps 2.4 kernel. I need to implement this
functionality for the 2.6 kernel. Temporarily  remove these lines in
/etc/network/interfaces and the port is powered.
To use the usb host functionality you have to do a modprobe ohci-hcd first.

warning: the ohci-driver lacks pm functionality, so remove this modules
befor suspend.
