Hi,

This is my third attempt to post this information to mailing list in a
little over a week. Am I invisible? Can nobody see my messages? I have
precisely followed the instructions posted on linuxtv.org/wiki/index.php/Em28xx_devices#How_to_validate_my_vendor.2Fproduct_id_at_upstream_kernel.3F trying to get my hardware validated. What else do I need to do? Can
someone answer please and help me.

Thanks,
--Ronald

Hi Ronald,

Well, probably nobody knows what to do with that ;)

If I understood well your post, video didn't work, right?

So, either you or someone else with the same hardware as you have would need to make it work and send a patch to the mailing list adding support for this new ID.

Probably, it is just either a GPIO or the video input that it is wrong. In order to fix it, you would either need some help from the manufacturer or to sniff the USB message exchanges from the original driver and check the settings for saa7113 and em28xx. The wiki has some info about how to do it.

Regards,
Mauro

Re: Call for help: em28xx: new board id [1f4d:1abe]

Hey Mauro,

Thanks for the reply. Relieved to know I'm not invisible. =)

I'm a total noob to linux driver issues, so if I'm posting this in the wrong area, please forgive me. I only posted here because this is where linuxtv.org said to go to ask for help. Until now all my hardware has just worked. So big thanks to all the people who made that happen! But this EasyCap board is kind of kicking my butt.

You are correct, when I plug this USB device in video capture device is not detected and so does not work. As I understand it, all the drivers needed to make this Easycap work in linux already exist and are used by various forms of Easycap devices already.

The em2860 USB video bridge chip should be supported by the "em28xx" kernel modules, and the Trident SAA7115H chip should be supported by the "saa7115" module. My best guess is that the card vendor:product id [1f4d:1abe] is simply not "attached" to those drivers or known by those drivers so when I plug this USB device in, video drivers are not loaded. But my assessment of the situation might be completely off here.

Couple questions...

First, if nobody know what to do with the information I've posted, why does linuxtv.org/wiki instruct me to post this information here, exactly this way? Not a big issue really, just quite confusing.

Secondly, if all the drivers already exist, what do I need to do to get them to "attach" to my hardware? Is there some place I can go to learn how to do that fairly quickly? Is anyone in this board knowledgeable about how that can easily be done? I am competent enough with linux that I can perform the steps necessary if I know what those steps are. This is new territory for me though.

Any help anyone can offer would be greatly appreciated! =)

Thanks,
--Ronald

Couple questions...

First, if nobody know what to do with the information I've posted, why does linuxtv.org/wiki instruct me to post this information here, exactly this way? Not a big issue really, just quite confusing.

Feel free to improve the documentation ;)
Just remember that the documentation there should be generic enough for people having different boards, specially if you're looking into a generic section of the Wiki.

Quoted 2 lines

Secondly, if all the drivers already exist, what do I need to do to get them to "attach" to my hardware?

Because of two things:

- the USB ID is used to identify the driver that will be used. If the driver doesn't know the USB ID, it won't be loaded.

- each hardware is wired on a different way. The saa7113 have 4 different video inputs (if I remember correctly). Also, there are several pins used on most video hardware called GPIO. They're used to power on and reset the other devices. The power on/reset sequence is board-specific.

Is there some place I can go to learn
how to do that fairly quickly? Is anyone in this board knowledgeable about how that can easily be done? I am competent enough with linux that I can perform the steps necessary if I know what those steps are. This is new territory for me though.

Wiki is your friend. Also look at other posts on the ML from other people that had to do the same.
