 Posted: Sat Jul 22, 2006 4:23 am Post subject: ov519 webcam not loading modules/dev [SOLVED] |
 |
|
I have been given a DSE XH5096 Internet Camera + Microphone.
Camera specs:
DSE XH5096 Internet Camera + Microphone
OmniVision Ov519 chipset
USB 1.1
24bit/16.7M colours/RGB
My problem is that while it is found and recognised by the system as a device, the required modules are not being loaded in by Udev/Hotplug.
As you can see below, the device is present, it just doesn't load the module/s or create the device, I assume /dev/video1.
I know that v4l and other required kernel bit are there as I have a working TV card on video0 and radio0.
When I modprobe ov511 and ovcamchip they install but do nothing except show up under lsmod without any tie-ins. | Code: | one rob # modprobe ovcamchip

udevinfo starts with the device the node belongs to and then walks up the
device chain, to print for every device found, all possibly useful attributes
in the udev key format.
Only attributes within one device section may be used together in one rule,
to match the device for which the node will be created.

golding,
Your camera provides a Video For Linux interface to the outside world so you need Video for Linux support in your kernel.
A module is fine.

I know, and it is modulated, as required by bttv, the other video device I have.

This is why I cannot understand why it will not work  Everything is in place as it should be.
If I plug the camera into the USB I get | Code: | tail -f /var/log/messages
Jul 22 19:42:39 one kernel: ohci_hcd 0000:00:02.0: wakeup
Jul 22 19:42:40 one kernel: usb 2-1: new full speed USB device using ohci_hcd and address 3
Jul 22 19:42:40 one kernel: usb 2-1: configuration #1 chosen from 1 choice |
| Code: | dmesg | tail -f
ohci_hcd 0000:00:02.0: wakeup
usb 2-1: new full speed USB device using ohci_hcd and address 4
usb 2-1: configuration #1 chosen from 1 choice |
Are there any conf rules I could put in modules.d perhaps, such as an alias or option?
Is there a requirement for both ov511 and ovcamchip, or a particular order with which they are installed? Not that I haven't tried these, but still wondering. The card definitely works, plugged it into Dads laptop (MS) and it fired up straight away. Not a bad picture for USB 1.1

golding,
Sorry about that - I should have reread your post
This site suggests that first there was ov511, which is in the kernel, then there was ov51x, on which development has stalled, now there is ovcamchip.
Try all three drivers
and see if a driver claims your cam. Entries in red have been detected by the kernel but not claimed by any driver. ov51x is supposed to cover everything that ov511 does and ovcamchip is a development of that. You are likely to need either oc51x or ovcamchip but not both.
Its possible your cam has a Vendor and Device ID thats not in the module, it may work if you add them.
Some modues all for that at module load time.
What does say about module parameters.
Its not usually difficult or harmful to the hardware to add more Vendor and Device ID pairs.
Look at the code and copy the format of whats there. It doesn't always work, sometimes, it really is a different chip.
============== Edit =======================
ov51x knows your Vendor and Product ID, so it should work. However, manufactuers sometimes change the hardware but not the device ID, so its an good sign but not gaurenteed.

Tis OK, have found my setup works now, tried mates webcam and it came up straight away, no probs.
It seems my 0v519 may/might/should, but don't hold your breath, work with the ov51x driver, will see tomorrow after some sleep.
Other than that, I'm changing the topic to [SOLVED] as it is the chipset, not the setup, that caused the problem.
Thanks for your time
