The probe of the si2146 tuner fails and returns 0xffs. Now I would like to work on fixing this. Mauro suggested the firmware might be incorrect. Any tips on extracting the firmware? I can try and dump usb traffic from Windows and see what firmware is being used there. How did you extract the firmware? Any other suggestions for this device? You might be able to save me a lot of time since you have experience with these types of devices, I do not. Thanks Sean
