(I don't remember what it was previously, but it seems wrong how can I be sure about that?). I have put back the driver to the original state, but still it doesn't work. Did I have to reprogram the eprom? If so, it is possible via usb? Thank you, Andrea PS I've found an old dmesg. The USB ID is wrong! The old one was eb1a:e323Ok, so that confirms that indeed the eeprom was corrupted. I would suggest you hack the USB_DEVICE() entry in em28xx-cards.c to be eb1a:e312. This will allow the driver to load and the i2c device to be setup. Then use the eeprom repair script to rewrite the eeprom. At that point you should be able to remove the hack, because the USB ID will be back to eb1a:e323. Devin
Ok Devin! It works again!!! If you come in Trieste, let me know and I'll pay you a beer :-)I can also confirm that the digital_defaul gpio does not work so the kworld_330u_digital gpio is needed. In any case I've an usbsnoop of this device but I don't know what I've to search in that 125Mb log text file. I've parsed it with the parse _snifusb2.pl tool and the result is the attached files. Still I don't know what to search to extract the gpio for analog and digital tv. If someone can explain me some basis, maybe I can validate the actual assumptions made in the driver as far as the gpio is concerned. In particular I suspect that the digital demodulator remains active when switching from digital to analog tv.
