A few times a month, my kernel suddenly decides that the USB device was disconnected and reconnected, resulting in the device getting a new number and causing my recording software to stop recording until I restart it with the new device number. Here is an example of the dmesg output when it happens: [1126917.418424] usb 2-8: USB disconnect, address 3 [1126917.444413] em28xx #0: disconnecting em28xx #0 video [1126917.445563] em28xx #0: device /dev/video4 is open!

Is this a known problem for this particular capture device or a potential driver issue? Should I be bugging the USB people instead of this list? Any ideas would be appreciated. thanks, -Ben Swartzlander -- video4linux-list mailing list Unsubscribe mailto:video4linux-list-request@redhat.com?subject=unsubscribe https://www.redhat.com/mailman/listinfo/video4linux-list
