Hello,
I'm the owner of a USB capture stick, the Hauppauge USB Live2. I've
been using this successfully on Ubuntu Lucid 32-bit using the 2.6.32
kernel,
where I was able to use tvtime and other apps to receive the output of
the card. It is using the cx231xx driver.
The (updated) driver is now part of v4l2. I'm now on Ubuntu Maverick
(2.6.35) and wanted to build this driver for use on this system.
I've built this driver on a netbook 32-bit and a 64-bit maverick
system, but no success. The following is output from kern.log when
the driver is loaded by plugging the stick in and afterwards lots of
errors when tvtime is started and it tries to get a video stream.
The relevant dmesg part is below.
tvtime starts up, but shows as a black screen. When it is running, the
kern.log keeps showing error messages related to the device:
Feb 12 09:27:51 olinda kernel: [ 2522.605193] cx231xx #0:
do_mode_ctrl_overrides : 0xff
Feb 12 09:27:51 olinda kernel: [ 2522.605202] cx231xx #0:
UsbInterface::sendCommand, failed with status --19
Feb 12 09:27:51 olinda kernel: [ 2522.605209] cx231xx #0:
do_mode_ctrl_overrides PAL
Feb 12 09:27:51 olinda kernel: [ 2522.605218] cx231xx #0:
UsbInterface::sendCommand, failed with status --19
I have confirmed the device is functional and working under windows 7,
which does show a good output as expected.
I hope someone will be able to fix it or otherwise provide a
workaround. If more information is required, please let me know
and what I should do to produce that output.
Rgds,
Gerard
