OV511 chip doesn't work with 2.6.11 :(

gungner · Post by **gungner** » Tue May 17, 2005 6:08 am

I just upgraded to Mandriva 2005 which comes with kernel 2.6.11 and my USB cameras doesn't work any more

I found this :

"ov511-2.28 driver does not work under linux 2.6.11 for three reasons: 1. remap_page_range does not exist (The log message is \"ov511: Unknown symbol remap_page_range\") 2. USB parameters idProduct and idVendors are kept in little endian format (previous kernels converted those data in cpu format) 3. usb_unlink_urb is deprecated (messages and stack dumps on the logs), usb_kill_urb must be used instead for synchronous streams. 1. and 3. affect all the systems while 2. appears only on Big Endian computers (with log error messages like: \"Unknown product ID 0x1105\"). I wrote a patch, see http://www.bononia.it/~renzo/keap/ Please insert the patch in the mainstream. Do not forget to put a tiny \"credit\" for the bugfix."

I'm a bit stuck now what to do, is it to recompile the driver and install the new one. Anyone done it already?'

cheers, tord

I have 2.6.11.8 kernel and driver ov511 (with Creative Labs WebCam 3) works fine.

That's good to know, thanks. When I plug my creative webcam III I get the following from dmesg.

It just doesn't work after the upgrade. How you upgraded or installed from scratch?

I have vanilla kernel from source with no patch.

thanks, I think I'm using version 2.28 which seems to differ from your setup. I'll try "downgrade" and see how it goes.
