It is a powerswitch that can be toggled via USB. Cleware also has
sensors (temperature, humidity, etc.) that all can be handled via a
commandline utility I wrote.
It has been a while but if i remember correctly the failing ioctl is for
determing the serial number of the device. That is required to talk to
the right device. http://www.vanheusden.com/clewarecontrol/
