Logitech Camera

Hi,

(v4l newbie here, so be relatively gentle with me !!)

I'm trying to get a "Logitech Pro for Notebooks" camera working under Debian 
(Libranet, apt-getted to "sarge"), and I can't seem to get the drivers to 
load correctly.

When plugging the camera in, I get the following;

--

Oct  1 06:18:38 orac kernel: hub.c: new USB device 00:0b.1-1, assigned address 
2
Oct  1 06:18:38 orac kernel: usb.c: USB device 2 (vend/prod 0x46d/0x8b1) is 
not claimed by any active driver.

--

I know this is probably a dumb question,. but has anyone else gotten on of 
these working ?

Jon

Have you installed & loaded a proper driver? I think pwc might support that
camera, but if not, there's a chance it's totally unsupported in Linux.

Avermedia 307

Hello, I am trying to get support for AverMedia AVerTV Studio 307 card. It is based on saa7134 with Phillips
1256 IH-3 (MK3) and tda9887. The card is very similar to MD2819, but there are some differences. So I attach
the patch with description of the card to make it properly autodetect.

Here is state of support for that card:

1. Video in generel is working fine. But it's recommended to add secam=d option to tda9887 module. There is
no questions about it.

2. ir-remote control also works with lirc-0.7.0pre7. It is difficult to create lirc config file, but
hand-made config works. Probably there is problem in irrecord, the full description can be found in lirc
mailing list http://sourceforge.net/mailarchive/forum.php?thread_id=5662019&forum_id=5339

Also there is problem related to modprobe, I wish to use ir-remote to control other applications, so I
want't to write alias to /dev/input/event2 in modprobe.conf

alias char-major-13-66 saa7134

but this, unfortunately, doesn't work, and I had to do modprobe manually before starting lircd.

3. Tuner doesn't work. Does someone get working tuner for MK3 series? For example, for 1216ME or 1236? 

First, I don't here anything with radio when using card=22 option. If you look in the patch, you'll see, that
.amux for radio is TV. Only after that change I can here noise from tuner when 
access to radio. Why I can't use LINE1/LINE2 there?

Second, even those manipulations don't give any result. I still investigating the docs and driver, but any
advice would be desired.

                                                 Shmyrev.

[Patch] AverTV Studio 303 (M126) - GPIO from DScaler

Have mail trouble, this is already one day old again.
Any mail that includes code never reaches the list and is silently dropped 
somewhere. It is not an issue with my filters or mail providers, because that 
still works fine under each other. So I try again with the last known working:
packed attachements. I'm sorry for that.

------------------------------------------------------------------------------

Hi Folks,

it happened yesterday evening between some mails that the DScaler team
got this card to work and Torsten Seeboth just send me the values that
we might enjoy it too. Thanks! (BTW he was on SuSe 9.1 trying latest :)

So time to get it out. Just kept it as it was with gpio3 first.
It is reported working with PAL-DK, don't know about Nicam and radio
yet. The tda9887 settings should come through with our defaults.

As I don't have the card and possibly messed it up, testers wanted.

Greetings,
Hermann

kernel 2.4 compatibility of video4linux

Hello,

recent video4linux CVS snapshots (tested the 20040930 and 20040923 ones)

Is there a chance to fix this?

Hi Dima,

if it did not reach you as an attachement, the spinics.net mirror also keeps it
http://www.spinics.net/lists/vfl/msg12600.html

It goes against cx88-cards.c of the latest 20040930-141712 snapshot.

This one has now the cx88-dvb compile issue solved, because the build is 
disabled for kernel < 2.6.9, but there is a remaining issue with the latest 
sleep timing changes introduced with 20040922. That causes an unresolved symbol 
error here for msleep_interruptible if not set back like in the latest 20040920 
snapshot. That one should be fine, but it has not yet a gpio0 value for 
Television. No issues with 2.6.9-rc3 at all, but that one should not be necessary.

If you like to try on older driver versions you have to change the tuner type 
to 38, also you have to check to use the correct expression for the presence of 
tda9887 and radio. That has changed meanwhile.

Greetings,
Hermann

Re: Logitech Camera

What is your kernel version ?

I had a problem with this webcam on Mandrake 9.2 kernel 2.4.22 with the
driver pwc (apparently the only one working with this cam): the system
was locked. The only solution i found was to switch off/on.
After looking on forums and kernel sources, i've found a problem with
USB managing (its noticed on pwc homepage or FAQ ?).
The USB problem seems to be solved by the kernel 2.6, but i have not yet
installed it, so i have a beautiful cam not working for now :(

To get away with the trace '...... not claimed by any active driver',
i've this line in /lib/modules/2.4.22-0/modules.usbmap
pwc                  0x0003      0x046d   0x08b1    0x0000      
0x0000       0x00         0x00            0x00           
0x00            0x00               0x00               0x00000000
obtained by compiling the kernel with the config option
'CONFIG_USB_PWC=m', i think adding it in /etc/hotplug/usb.usermap.local
as the same effect
I have also added in /etc/modules.conf
alias char-major-81-0 pwc
post-install pwc /sbin/insmod --force /lib/modules/usb/pwcx.o >/dev/null
2>&1  || :
options pwc size=vga fps=15 fbufs=3 mbufs=2 power_save=1
below pwc videodev snd-usb-audio

Sorry, I don't know the equivalence of these files on a Debian

Good luck

setting TCL 2002N tuner's frequency

I'm attempting to use Hauppauge PVR-250 I purchased recently for NTSC
cable in US.

Elsewhere it was noted that this newer rev card uses TCL 2002N tuner
different from former revs and not supported by released V4L. Then I
found the support in recent CVS snapshots and tried
video4linux-20040927-171556 and it somewhat worked, but the frequency
setting were way off almost by 100Mhz.  While looking at it qfurther
today, I noticed that there are new snapshots with changes in this
area so I tried 20040930-141712.  Much better but not quite.  Now it
is consistently off by exactly 1Mhz for all the channels (330.25 to
watch 331.25).

Looking at the bytes going across and seeing what's happening in
set_freq, I modified the IFPCoff for the tuner to 716 instead of 732
and now it is right on.  Without understanding those numbers I doubt
this is the right fix.  I'm interested in having this card work with
V4L off the shelf, so if somebody knows a right way to fix this, I'll
be glad to test patchs and/or gather more information on my card.

Re: setting TCL 2002N tuner's frequency

I can't comment on the correctness of the change, but I was running 
20040930-141712 with my TCL 2002N and was just about to give up using 
the tuner (and use composite only) when your patch came around. Before, 
I could only get chan 5 vid/aud clear, chan 6 with audio sometimes, and 
sometimes audio on 3 and 4, but no vid. Now I get every chan except 5 
and 6, while 4 and 5 seem to have some issues with audio.

It would seem something is still off with those freqs, but CBS is the 
only chan I would miss out of those chans, so this is a big 
improvement.

If you need somebody with a TCL 2002N to test something else, let me 
know.

Thank you very much!
