Re: Dependency bug in the uvcvideo Kconfig

[Peter Senna Tschudin]

Hi Randy,

I've tried to download the .config file from the link on the forum,
but it tries to install something in my browser and the file is not
downloadable for me. Can you provide it over an simpler interface such
as pastebin.com?

Thanks
