The issue of webcams not working with recent kernels on CentOS 6.6 has come up a number of times on the list. I'm happy to report that the latest kernel (2.6.32-504.8.1) appears to have fixed the problem. The relevant changelog entry is: - [usb] ehci: Fix a regression in the ISO scheduler (Gustavo Duarte) [1162072 1145805] The related CentOS bug report is here: http://bugs.centos.org/view.php?id=7815 Ron
