Also the output of lsusb -v -d 0408:4035 Thanks! > > > Installed linux-source but uvc_driver.c I found in the directory tree of Ubuntu is different from both : > > - https://github.com/torvalds/linux/blob/master/drivers/media/usb/uvc/uvc_driver.c > > - https://patchwork.kernel.org/project/linux-media/patch/20220617235610.321917-9-ribalda@xxxxxxxxxxxx/ > > > I would like to test your patch and see if the solution can be submitted to Ubuntu for the next fix release. > > -Could you give me some instructions on how to proceed ? > > -Should I compile a new whole kernel or just a mod? > > -Where can I find the source to which your fix applies (seems to apply to something different from Ubuntu and torvald versions) ?
