0c45:627f - Lenovo 3000 N100

[Diego Iastrubni]

Hi all, meet test bunny.

Test bunny has Lenovo 3000 N100 with 0c45:627f.
Test bunny has pulled latest code from git, which does not contain
support for his webcam.
Test bunny changed the code of the driver to use 627b initialization
code. It crashed his machine.
Test bunny is willing to help as mush as he can, and is using
2.6.24-16-generic (ubuntu 8.04 32bit)
Test bunny can give direct SSH connection to his machine.

:)

But test bunny shouldn't actually do so with people he just met in some
weird google group. ;-) Especially since debugging will most likely need
root privileges.

Hi there

In windows *.inf file I've found: 627f means sn9c201 + eeprom

We definitely need some usb-snoop-logs from you :)
Can you boot into windows and make some cool usb-snoop-logs for our
project? :) Follow this manual:

That's ok, displaying non black images was a pre-condition I would easily guess.

I am running currently Vista32 and I cannot install the *sys driver for the capturing. I used version 2, from http://www.pcausa.com/Utilities/UsbSnoop/SniffUSB-x86-2.0.0006.zip as described in that manual.

If this does help (?) Windows Update found a suitable driver for this cam called "ASUS WebCam 1.3M USB2.0, FF". That worked but I decided to install the Driver supplied by Lenovo anyway.

Again, I am under the impression that you think I don't know what I said in previous mail. I don't have a problem with some developer logging into my machine and crash it a few times, if eventually it gets me a working web cam. I think a reverse SSH connection will help, but I can stop being lazy and I should forward the correct port from my laptop to the FW :)

Hi Diego

Are you sure that you have 0c45:627f ?,
instead of the more likely 0c45:624f ?

Can you try with 0c45:624f init/start/stop stream sequences ?

Also few users have reported problems with 2.6.24.x kernels,
can you try on 2.6.22.x ?

Nope, I've seen one more lenovo 3000 n100 with 627f cam. 624f functions don't
work for it.

Please try "Device monitoring studio"

http://www.hhdsoftware.com/Products/home/usb-monitor.html

[Diego Iastrubni]

I installed that application, and recorded a few seconds of video. I am attaching here the "export" of the packets dump (if I understand this application).

However, it seems you guys are looking for the initialization string, and the document you sent me to, asks to unplug the device. Since this is a built-in webcam, this is not possible. How can I help you? Just ask.

I will verify the lsusb output, and I will test other initialization sequences in a few hours, or maybe tomorrow.

No, we need "urb view, detailed". Here's manual:

Just install device monitoring studio, reboot your laptop.
Start device monitoring studio, add "urb view" plugin for camera device. Start
sniffing on usb device. NOTE: do NOT start any video app before starting
sniffing in device monitoring studio.

Then open any video app, wait until you'll see something. Image should be
stabilized, i.e. brightness should be OK. Then close this app.

Stop usb-sniff in device monitoring studio. Export detailed info as *.txt
(ansi) file. It will be huge - ~300-500mb. Compress it with 7zip or with rar
(7zip preffered). Then upload it somewhere where we can get it. Please, DON'T
send it to the maillist.

God I hope you don't mean port "rmmod" to win32 to unload the driver... :)

What are you exactly suggesting? The best idea I have is to uninstall the driver, reboot windows, start capturing, install the driver and then hope for good.

I am open to suggestions.

[Diego Iastrubni]

7zip will compress much better then bz2. You have a free unpacker on every debian based system. If you don't have debian installed, debootstrap is your friend :)

[Vasily Khoruzhick]

Nope, 7zip compressed my 300mb device monitoring studio log to the small 4mb
7z-archive, but gz compressed it in 20mb archive. Btw, 7zip is lgpl
software ;)

Hi Diego

How about Linux with virtualization for windows XP 32-bit,
then we can connect/disconnect usb devices via menu,
(usb 2.0 is a problem)

then just usbmon will do to capture the init/start/stop stream sequences.

[Diego Iastrubni]

I tried it once with VirtualBox and was not working. Anyway, this kind of setup requires a lot of work, and will take me a few days to get working (install XP, and all zillion drivers). I still did not manage to find time for that original test.

I have been thinking... maybe enabling/disabling the driver via the control pannel will have the same effect. I should try it.

[Diego Iastrubni]

I rebooted the machine, started capturing, and opened MSN and the cam settings page. IMHO should be enough. It's only 4MB.

On my cam (624f), there's a hardware button on the cam itself that
will cause the device to disconnect from the USB bus.
