Some comment about the driver:
In general you could cleanup the thing a little. There are some strange
things which should be written differently to make it easier for others to
read (and also to please kernel people). For buffers you should always u8
not char.

+static u32 last_key_pressed=-1;
You cannot do that, because if you plug two devices at the same time, they
will both use the same global variable. Things like that have to go into
a private struct allocated for each device. You can you the size_of_priv
field in the dvb_usb_device_properties to let the dvb-usb-framework
allocate it.

You could use *data here to do the transfer. Use u8 for local buffers.

Do not abuse i2c_messages for doing USB-transfer. I2C is dedicated bus
with a standardized interface (i2c_address, buffer). The I2C Adapter in
the linux kernel should only be used to represent the real I2C-bus inside
a device.

It is obvious something is wrong here. msg is an array of two messages but
you only give 1.
It would be much better to dvb-pll to program the tuner. If for your tuner
is not implemented yet it can be easily done.
To use dvb-pll you need to implement the i2c_adapter of your device properly.

+ }
+ i2c_transfer(&udev_adap->dev->i2c_adap, msg, 1);

I'm sure the LNB-controller on your board is already implemented... Please
use the existing implementation (also you need the i2c-adapter properly
implemented for that).
