I bought a fancy refurbished Acer laptop at a nice price. Ubuntu Feisty Fawn likes it all except the webcam, which is identified as 0402:5602, also known as m560x.

Well, I want it to work. I also want to improve the linux kernel, but I won’t be the one writing the driver, so instead I’ll use some of what I saved on this laptop to offer a bounty to the chap who does it.

I’ll pay by paypal $150 when Greg Kroah-Hartman of the usb-devel mailing list, or one of his deputies (e.g. Jiri Kosina) accepts working patches for this webcam and commits them for the upstream kernel; and where with the said patches I can get xawtv, ekiga and the like to enjoy the video source. like any other standard video source. The patches must be licensed under the GPL2, or GPL2 or later. The author retains copyright (naturally) or assigns it to the FSF.

To qualify, the patch, and earlier patch candidates (yes, they will make you tweak it and re-submit) must be submitted on the usb-devel mailing list, and excepting complications, the paypal payment will be to the email address comprising the Signed-off line in the patch submitted on said mailing list. I’ll split the bounty as joint contributors can agree or failing that, at my discretion. I expect one developer will leave a clear trail on the mailing list, terminating with the accepted patch, making recognition of the deserving author and subsequent payment easy.

The bounty offer will end after a valid claim has been made.

In any case it’s my intent to pay up to $150 to encourage development of such a driver and to pay it to those who write it and release it for kernel.

(It’s been suggested that this may involve working on sane-devel as well as usb-devel, in which case patches may need to be accepted for upstream submission by maintainers of both projects to qualify).

Information for starters:

• Someone doing a SANE backend.
• Info about a seemingly expired actiongames project to write a driver.
• People on linux-projects begging for a driver, in the presence of one Luca who claims to have one (sort of).
• A nicely collated list of all the webcams that use the said chip.
• Someone else begging for a driver.
• More people begging for a driver.

Of course I’ll post the bounty notice in some of these places too.

UPDATE
I’m advised by one of the developers that more likely two drivers, m5602 and m5603 will hit the kernel; unknown timescales.
As long as the 5602 is supported I don’t mind splitting the bounty fairly between contributors of both drivers; in my view it is a common work that is now more conveniently expressed as two modules instead of one.
I expect other contributors will feel the same was as long as their device is supported.
