I have that message in my /var/log/dmesg too, once for each device I have attached, minus one. Took a quick look, the message comes out of init_i2c_module() in go7007-driver.c

[ 17.653449] go7007-usb: probing new GO7007 USB board [ 17.653459] go7007 1-1.1:1.0: firmware: requesting go7007fw.bin [ 17.995726] go7007: registering new Plextor PX-M402U [ 21.101376] go7007: probing for module wis-saa7115 failed [ 21.101871] go7007: registered device video1 [v4l2] [ 21.101922] usbcore: registered new interface driver go7007 This is the error in relation to saa7115 module. I do not seem to have any problem using gorecord despite this error although I have not yet tested a long capture. However, I read somewhere that it is important that there be no error messages with the firmware load. What is the purpose of saa7115?? Thanks Hi Jelle,

Just wondering whether you can shed some light on the following error.

[ 17.653449] go7007-usb: probing new GO7007 USB board

[ 21.101871] go7007: registered device video1 [v4l2]

This is the error in relation to saa7115 module.

I do not seem to have any problem using gorecord despite this error although I have not yet tested a long capture. However, I read somewhere that it is important that there be no error messages with the firmware load. What is the purpose of saa7115??

Thanks

Yes, I can easily use gorecord to capture the video and then use kdenlive or similar to edit it. Thanks once again. jelle, thanks a lot for explaining the issues surrounding go7007.

That means that, with this driver, software needs to specifically know about this device and have a special piece of code to handle compressed video from it. That is precisely the main reason why this driver is not already in the official kernel distribution. I'm not even sure if kdenlive has support for anything but uncompressed data from v4l2 devices, and I would be very surprised if it had special support for this device. So, this particular version of the driver needs software that specifically knows how to handle this device. gorecord can, mythtv can, maybe other software can, but it won't be very many programs. What this driver really needs is to have the standard compressed video controls added, then probably quite a lot of software will be able to use it. What I did here on this blog is just post what I did with the driver to make the device work for me with newer linux kernels, and I only use it with mythtv. I also get the "unsupported ioctl" messages in the kernel log. IIRC, They always have been there, even on the older kernels with the wischip manufacturer supplied drivers. The device works anyway, so I consider them harmless, but I don't know which exact ioctl triggers that... gdesilva, the go7007 device can not do uncompressed video, and this version of the driver does not do compressed video using the official v4l2 interface for it.
