[linux-dvb] em28xx frontend does not attach

[-- Attachment #1.1: Type: text/plain, Size: 5186 bytes --]

Hello.

I have recently upgraded my Debian Lenny from kernel 2.6.25 to 2.6.26.
After this, I couldn't use my Cinergy Hybrid T USB XS (0ccd:0042).
Up to now I used the mcentral.de driver, now I would like to switch to
linuxtv driver.

Following the wiki "How to install DVB device drivers, and "How to build
drivers from Mercurial", I have cloned v4l-dvb. Make and install ran
smoothly.
I have generated the firmware from
http://www.steventoth.net/linux/xc5000/HVR-12x0-14x0-17x0_1_25_25271_WHQL.zip, Driver85/hcw85bda.sys

em28xx installed correctly, dvb frontend did not: zl10353_read_register
returned -19
Below the relevant dmesg section (em28xx modprobed with core_debug=1

Wrong firmware. You want XC3028, not the XC5000.

It doesn't matter - the Cinergy Hybrid is known to not work.  It's on
my TODO list, but this is complicated by the fact that I have neither
the hardware nor the DVB-T signal to debug the issue with.

Patches welcome, of course!

Cheers,

Devin

For the record, the device works properly with the code from mcentral.de.

It is probably not that complicated for you to fix the Cinergy Hybrid entry at
v4l-dvb.

You'll need to use usbsnoop tool to capture what the original driver is doing
[1]. 

After that, you can parse the log and fix the initialization values for
GPIO and GPO registers. You can also load em28xx with reg_dump=1 and parse the
dmesg output with the em28xx parser, comparing to what the windows driver did.
