I'm having the same problem, on Ubuntu Server 11.04 x64, kernel
2.6.38-10. I've also tried Debian with the same results. Here's the
debug log from the Ubuntu installation:

This is with the stock kernel, no media_build tree installed (I'm
currently compiling it).

Hello,
I'm using a Hauppauge USB live2 video capture stick with Ubuntu 11.04,
netbook edition.
On Ubuntu 10.04, I pulled v4l from a development mercurial branch,
where cx231xx drivers were provided. That worked ok.
Ubuntu since then was upgraded to 10.10 with kernel 2.6.35, which is
where I couldn't use that branch anymore. Since the driver was
upstreamed,
I decided to give the media_build branch a go. I ran into problems
trying to compile media_build on 10.10, because that uses kernel
2.6.35,
and decided to upgrade to Ubuntu alpha 11.04, which uses kernel
2.6.37, so that the v4l would be better supported.
After deactivating two modules in .config that created some problems
in media_build, I was able to get a successful build and 'make
install'
them. After a reboot and sticking in the capture stick, tvtime, xawtv
or other applications do start, but only a black screen is the result.
The standard camera from the netbook itself does give output, so it's
not likely an overall video or X issue. I tried to remove the stick,
replug it back in,
replug it into different ports, start up with the stick already in,
but nothing worked. The output @ dmesg is always the same and repeats
itself infinitely.
dmesg and lsusb information is attached.
Further details:
- hardware: Siemens N210 netbook (has another built-in camera @ /dev/video0)
- Ubuntu 11.04 netbook edition
- Linux 2.6.37-12-generic 32-bit i686 GNU/Linux (stock kernel that
comes with Ubuntu 11.04)
- Code pulled from "media_build.git", cloned yesterday
- Hauppauge USB Live2 video capture card, using cx231xx driver.
Are there any workarounds or quick patches available, or is the best
bet to revert to 10.04 for now?
Rgds,
