[linux-dvb] [PATCH] support Cinergy HT USB XE (0ccd:0058)

Albert,

your dmesg-output looks absolutely fine for me (besides the already discussed xc2028 4-0061: Error on line 1063: -5
message).
Since you also obvisouly succeeded to patch the xc3028 firmware so that the scode can be loaded (which in my
cinergy did not make any noticeable difference), I still have the suspicion that the dib0700-firmware is the main reason
for your device not working.
Can you try the firmware from the Windows-driver? Comparing various dib0700-based device drivers, I found quite
different dib0700-firmware in these. I am not sure if there is any single "latest" version of the firmware which can be used
for all devices.

I have written a small tool to extract the dib0700 firmware from the Windows driver (there are probably already other/better
tools around, but I just did not find any). If you use this tool (ignore the warnings, I am still trying to understand how the
firmware is organised) and then copy the resulting firmware to the firmware-directory under the name of
dvb-usb-dib0700-1.10.fw, do you see any difference?

Good luck,
Hans-Frieder

Here comes the tool:

/*
   dib0700 firmware extraction tool
   extracts firmware for DiBcom0700(c) based devices from .sys driver files
   and stores all found firmwares in files dibfw-00.fw, dibfw-01.fw, ...
