Making it Work

The Window drivers for this devices from TechniSat is named UDST7000Bda.sys, the same as the driver for the Technisat SkyStar USB 2 HD CI and TerraTec S7 DVB-S devices. These devices are supported by Linux with the az6027 driver. This gives some hope towards future Linux support for this device.
