I've the windows drivers WDM_Capture_220A.sys and WDM_Loader_220A.sys,
is it posible to get the firmware out of these?

When I start this program 2 usb devices are shown. Digital-TV Loader
and Digital-TV Reciver.

When I plug the usb stick, first, the Loader´s "present" present flag
is "yes", and this is the log I get:

.

When I start the usb sniffer 2 usb devices are shown. Digital-TV
Loader and Digital-TV Reciver.

When I plug the usb stick, first, the Loader´s "present" present flag
is "yes", and this is the log I get:

In a few seconds the preset flag switches to no an the Receiver
apperas as present.

This is the log I get 10Mb during the channel scan:
