em28xx in v4l-dvb destroyed my USB TV card

Hi all,

A problem with the em28xx driver was brought up in June by Thorsten
Hirsch: http://www.spinics.net/lists/linux-media/msg20588.html . I also have a "TerraTec Cinergy Hybrid T USB XS". When I used my device with Linux, it would take a long time to be recognised by the OS, and this would get worse. At this point, the device is not recognised, and almost completely dead.

When I plug it in, I get errors like
---------------------------------------------

----------------------------------------------
and these keep coming until the device is removed. The device is also not available in windows.

I have attached an excerpt from /var/log/messages , when the device was connected, before it was destroyed. Here is some more contextual info:

uname -a:
Linux muon 2.6.32-24-generic #41-Ubuntu SMP Thu Aug 19 01:38:40 UTC 2010 x86_64 GNU/Linux

Driver: v4l-dvb. The install process from linuxtv.org leaves me oblivious of the version number, but I used the most recent version as of a few weeks ago.

Firmware: I have "linux-firmware-nonfree" from Ubuntu installed, but I don't know if v4l-dvb replaces the firmware file.

I have a different version of the stick than what was mentioned in the above link: USB ID 0ccd:005e. In the post at
http://ubuntuforums.org/showpost.php?p=7832485&postcount=3 , it is stated that this version requires a different firmware: . In my kernel log it says that
xc3028-v27.fw is loaded, I think this could be the problem.

I was hoping someone could provide insight, or an explanation, and maybe (but not likely) a way to resurrect my device. I hope that someone could either 1) refute this problem with their own anecdotal evidence, or 2) actually remove support for 0ccd:005e from the driver, to prevent this from happening to anyone else.

I know this is a bit off topic, but if anyone could recommend a cheap replacement DVB-C card for a laptop, that definitely works with Linux, that would be great.

Many thanks,
Marius

Hi,

The "unable to enumerate USB device on port ..." error message usually means that the USB hardware what you connect itself is damaged. At that time the v4l-dvb driver is not yet started, only the low level USB enumeration is running. It is also possible that the USB cable causes the problem, if any. I had an USB device which had wrong soldering and that one gave the same error message. That device was degraded as time passed.

You might want to try the device on different USB port, different USB cable, or even on different computer to see exactly which hardware component is not working properly.
