Hi Antonio, I think I see why the commit prevents the webcam to work: as it is done, the choice of the alternate setting does not work with bulk transfer. A simple fix could be to also check bulk transfer when skipping an alt setting in the function get_ep(). About audio stream, I do not see how it can have been broken. Might you send me the full USB information of your webcam? Best regards. -- Ken ar c'hentañ | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/
