You can get the firmware via the following procedure: http://www.linuxtv.org/wiki/index.php/Xceive_XC3028/XC2028#How_to_Obtain_the_Firmware or if you're on Ubuntu it's already packaged in linux-firmware-nonfree. The file itself is 66220 bytes and has an MD5 checksum of 293dc5e915d9a0f74a368f8a2ce3cc10. Note that if you have that file in /lib/firmware, it's entirely possible that the driver is just broken (this happens quite often). The values read back by dmesg are from the device itself, so if the chip wasn't properly initialized fields such as the version will contain garbage values. Devin -- Devin J.
