i have a pavilion dv9722eg laptop with, and i'd like to help.
i tried to extract the firmware, but i haven't found the mentioned
file. how can i found out, what file would be helpful/needed?

Strangely, my webcam worked only one time, once I installed it worked
with success... I notice that time it loaded the firmware correctly,
but once I rebooted I just cannot load the firmware and I only get HP
Pavilion Webcam (UVC - NO FW).
Keep up the good work, getting really close now!

Ok. Tell me if I can help you in anything. Tks for your work.

joaoborsoi: Yes, at the moment, it's incomplete.

It works for me also. But I can't use it with skype. Is it because
it's unfinished or there is a work around? 
Tks.

New try for a usb log from windows. Hope this is a readable format:
http://dv6597.netia.es/up/usbsnoop.coldboot.log

I used sniffusb (http://www.pcausa.com/Utilities/UsbSnoop/default.htm)
but if you know a better program, please, tell me.

I had to cut lot of lines in the middle (I think packets of video)
If you need it all, please tell me and i'll compress and upload it again.

Cheers.

So close, but no cigar! :)
This error seems a bit more of a pain in the arse compared to the
other problems. 

From the looks of it, seems to be a problem with the way its getting
the packets back from the webcam (obviously). Not sure how to solve
this at the moment.

Could you get us a text dump from usbsnoop or whatever you used in
the first one from a cold boot? The one you attached here (not XML)
was in binary, and I can't read that. Sorry.

this is the beginning of the dmesg output:

after a while seeing myself xawtv halted with this error:

I've set it so that hopefully it won't bomb out if it can't set a

First of all, thanks to you for your time. It's my pleasure.

/dev/video0 not created. Cannot launch any tv app.

Looks like the camera doesn't support some of the UVC controls (ie
brightness, contrast, hue, vflip, etc).

I've created a separate control list for the camera in the latest
revision, so, hopefully, it'll get a bit further (and possibly capture :)

It's also probably easier if you just used tvtime or xawtv to test
the webcam instead, since uvcview has issues with some of the cams,
and the args you passed to mplayer don't match the image format
returned by the camera (so, if you got passed that error, it'd still
fail trying to display an image).

I finally got the right module to load. I had some problems with the
versions. r61 initializes correctly the device. This is the output:

Marked as blocker for next release.

The only possible way you got that output is if either you didn't update
correctly or its detecting a 1810 device instead.

You sure you're updated all the way?
In the latest code I have (synced to the server), and 1812 is associated with
R5U870_DI_HP_PAVWC_UVC_1 in the table, which should have the model "HP Pavilion
Webcam (WDM - NO FW)" rather than "HP Pavilion Webcam (UVC)".

I'm trying r60 now. No result. dmesg output to sudo modprobe r5u870 debug=1
after compiling without errors:

I realized that the id_table is still associated 1812 with the same as 1810. I
tried to change it to "right". Exactly the same output. I will try to use usbsnoop.

Seems as though the 1812 device doesn't really need any microcode stuff.
Either that, or I need to get some fresh dumps.

Marking as needing testing.

Progress in working out the protocol is on
http://wiki.mediati.org/R5u870/1812_Protocol

At the moment, I've done a bit of hackery in r5u870.c
Basically, I just need to get the correct firmware happening (at the moment,
current one seems to be buggered and return -32).
