UVCVIDEO patch for Imaging Source CMOS camera

[superman4321]

Hello all,
I am new to linux and trying to use Imaging Source CMOS USB camera on my laptop. The problem is it does not have any drivers for linux and upon some google search, this website provides a patch for uvcvideo to make this camera work(unicap-imaging.org/tis_devices_en .htm) Its a CMOS camera
So, I followed all the steps, but when I use the patch it says 7 out of 7 HUNKS failed.
Does anyone know why this is happening?

(Steps:
Cloned git media_build repository as shown on the page.
Downloaded patch
$ patch < /home/myusername/Downloads/uvcvideo_add_tis_cmos.patch

I have sent a message to Imaging Source for more information, leveraging my business connections. Perhaps I'll be able to get some satisfaction for you, but no guarantees. Hopefully I will hear from them in a day or two.

Ok. The Imaging Source has been very cooperative in providing information about this. This is what I have found out from Scott Bradley, one of their support engineers.

1. They are working with the Linux kernel developers and the developers of the uvcvideo drivers to make these devices work "out-of-the-box".
2. This is a work in progress, but when done, all USB video cameras such as theirs will work without problems.

I am currently waiting on an ETA for this capability, but my feeling is that if you are patient, you will have what you need in a few months (we hope!). Anyway, any further updates from Scott will be passed along to this thread.

Thanks Rubberman.
I was successful in patching the driver, but the camera still didn't show up when I typed in ls /dev/video*. So I guess I will probably have to use some other camera since I am short on time.
But yea, that's good to know that they are starting to roll out support for linux as well.
Thanks again for your time. Much appreciated!

I got another email from them about this stuff. Here is a copy for your information.

I was forwarded your request regarding the Linux support of our cameras.

Our USB CCD cameras are UVC compliant but they do not advertise in the USB descriptors as such. Thus
the uvcvideo driver needs to be patched to detect the cameras. The patch is submitted to the
maintainers and will be included in a future version of the mainline kernel. In the meantime, you
can get the patch and instructions on how to apply it here:
unicap - The uniform API for image acquisition devices

The USB CMOS cameras are currently not UVC compliant and are only supported by a userspace driver
that is included with unicap. But there is currently an UVC compliant firmware version in the works
that will be available as an update for existing cameras by the end of February. With this
modification, the cameras will be detected by an unpatched uvcvideo driver. Keep in mind however
that the cameras only provide a RAW image so software support for color interpolation is required.

Please let me know if there are any further questions.

Best regards,

Since I don't have one of these doohickeys, I don't know if this will help, but I do have to say that their people responded quickly, and with what seems to be relevant information. Let us know if this helps you sort it out.

Did you ask him about UVC firmware for CMOS cameras?

UPD:I have found firmware docs here: _unicap-imaging.org/fwupdate.htm (originally from _unicap-imaging.org/blog/index.php?/archives/7-Installing-USB-Cameras.html)

I only know what they told me from my posting below. I haven't heard anything more from them.
