Hi, i think there you are right - without the workaround the camera(s) worked great. But i get nothing from the webcam - also no corrupted image :( - just the Apr 28 13:02:09 blah kernel: cpia.c:parse_picture(1947):EOL not found giving up after 1350/81428 bytes. And because the cpia driver is in the kernel source and the problem seems to be the amd viper usb controller, i dont know who to ask except this list.
