Hi, I've launched a "yum upgrade" command on a CentOS6 laptop which has updated nearly 600 packages. Automatic updates were not working because of a conflict on a package. So the laptop is now uptodate but the camera did not works after this. The message is: kernel: uvcvideo: Failed to query (GET_DEF) UVC control 6 on unit 2: -110 (exp. 2). The camera is detected as USB, lsusb shows: Bus 001 Device 003: ID 0c45:646b Microdia I've tryed to boot on alternative kernels but no change: - vmlinuz-2.6.32-504.3.3.el6.centos.plus.x86_64 (which solve a camera problem on my laptop) - vmlinuz-2.6.32-431.29.2.el6.x86_64 - vmlinuz-3.10.63-1.el6.elrepo.x86_64 Any idea about a faulty package ? I've added the upgrade log in attachment but it's quite big. The first four erased item were because of conflicts. Some are re-installed after the upgrade (end of the log file) Thanks Patrick -- =================================================================== | Equipe M.O.S.T. | | | Patrick BEGOU | mailto:Patrick.Begou at grenoble-inp.fr | | LEGI | | | BP 53 X | Tel 04 76 82 51 35 | | 38041 GRENOBLE CEDEX | Fax 04 76 82 52 71 | ===================================================================
