Webcam HP Pavilion dv6520ez

FenDanT · 2008-01-16 23:02:16

Hello

Serching for weeks for a solution for ma webcam.

Here is the lsusb :

Bus 001 Device 002: ID 05ca:1812 Ricoh Co., Ltd

Very strange, but it's very hard to find something about it.

I found some tricks about another Ricoh's webcams (1810, 1832...) but nothing about 1812...

I found that some of others Ricoh's webcam could work with the r5u870 driver,

I found the source here :

http://ubunteros.free.fr/r5u870-0.10.0.tgz

I unzipped it and made a make as user and a make install as root. But i have an error telling me that /lib/firmware doesn't exist. So i created it and made a make install again.

So yet à have a lot of files in /lib/firmware like that r5u870_1810.fw : 1810, 1830, 1832, 1833,1834, 1835, 1836, 183b, 1870 et 1870_1. But nothing again about 1812

Anyway i tried

modprobe r5u870

but with no results at all

I made some tries with uvc too, but nothing again. Only a lot of problems in Archlinux...

So i'm trying to find some help here.

If you have somme ideas, please feel free to give some answers here... I'm a bit deseperate with this webcam

Try this :

svn checkout http://svn.berlios.de/svnroot/repos/linux-uvc/

then

cd linux-uvc/linux-uvc/trunk/
make
make install
modprobe uvcvideo

or

pacman -S linux-uvc-svn

Hello ronai

And thanks for your response.

I'm not sure waht i have to do with the first part of your response... Do i have to download your link ?

Anyway, in the same time i tried this :

[root@cave jacques]# pacman -S linux-uvc-svn

Sorry, it's in french but i think it's like a segmentation error or segmentation faults ?

some guy recently picked up r5u870 and added some pathces, you might want to check this out
http://wiki.mediati.org/R5u870

Hello

So yet i had to desinstall linux-uvc... It caused some problems on my laptop, especially with the modprobe or rmmod commands, blocking those commands.

Impossible for me to do a modprobe r5u870, it took a long time, with no results... So yet without linux-uvc, anything seems to be all right.

I tried this link from hacosta http://wiki.mediati.org/R5u870, but my 1812 isn't in the list of supported devices.

I tried anyway to download the source i and have made make and make install with this version. But with not more results as before.

I try to understand what i exactly have to do with this page http://wiki.mediati.org/R5u870/Extracting_firmware. It seems to be a bit hard for me, but i'm ready to test it.

My first problem is to find the good windows driver for my webcam. This laptop was made by HP to run only with Vista, so thes dont want to give another driver, for XP for example.

I'm not sur if i can find it under Vista, and what kind of file i must search. I try on HP's site too... Here the link in french http://h10025.www1.hp.com/ewfrf/wc/soft … 69&lang=fr and the same i think, in english http://h10025.www1.hp.com/ewfrf/wc/soft … 69&lang=en.

But where is the driver for the webcam ? I made this search with the exact model name for my laptop : dv6520ez.

Another small question : what kind of software do i use to test my webcam after the modprobe r5u870 ? I only have tried with Koppete, hoping that the problem isn't with Koppete...

Did someone solve problem with Ricoh webcams in HP laptops already?

chris_ak · 2008-03-27 01:40:28

I have this exact webcam and had it working fine under ubuntu using the r5u870. It worked fine for skype. I haven't tried it under arch, but I'm assuming with a little work it would be just fine. I really have no use for my webcam so I'm not going to bother with it - but I suggest scouring the ubuntu forums and you should find a decent howto for this webcam.

i have this exact webcam and had it working fine under Arch using the uvcvideo

i just compile the driver from the source and use wxcam

Hello mauud777

Are you sure you have this exact model :

Bus 001 Device 002: ID 05ca:1812 Ricoh Co., Ltd

?

If yes, can you give us some details about the correct install and use of uvcvideo ?

Thanks in forward, because i spent so much time finding an working issue

Kardell · 2008-03-28 17:52:37

Yeah, it would be very helpful.

i am sorry

main is :

Bus 007 Device 002: ID 04f2:b015 Chicony Electronics Co., Ltd

just try to install linux-uvc from source then restart

if you want GUI program for cam the best program from my experience is wxcam you can find it in AUR

FenDanT · 2008-03-30 15:00:36

Hello

Too bad... So it wont works for us with uvc

Kardell · 2008-03-31 16:49:23

Yeah
This is the weak part of Linux operating systems - lack of drivers (drivers for home-use hardware).
Microsoft even is doing a crap, they always take care of drivers + simply they`ve got manufacturers support.
