Thank you for the quick response. Hmm, I am not seeing anything about the saa7113 or similar chip. I just replugged it, and here is what showed up in the log: Mar 3 19:32:45 home kernel: [122185.832751] usb 2-3: New USB device found, idVendor=05e1, idProduct=0408 Mar 3 19:32:45 home kernel: [122185.832762] usb 2-3: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Mar 3 19:32:45 home kernel: [122185.832769] usb 2-3: Product: USB 2.0 Video Capture Controller Mar 3 19:32:45 home kernel: [122185.832774] usb 2-3: Manufacturer: Syntek Semiconductor Mar 3 19:32:45 home mtp-probe: checking bus 2, device 4: "/sys/devices/pci0000:00/0000:00:04.1/usb2/2-3" Mar 3 19:32:45 home mtp-probe: bus: 2, device: 4 was not an MTP device Mar 3 19:32:45 home kernel: [122185.885397] usb 2-3: New device Syntek Semiconductor USB 2.0 Video Capture Controller @ 480 Mbps (05e1:0408, interface 0, class 0) Mar 3 19:32:45 home kernel: [122185.885408] usb 2-3: video interface 0 found Mar 3 19:32:45 home kernel: [122186.456571] stk1160: driver ver 0.9.5 successfully loaded Mar 3 19:32:46 home kernel: [122186.589683] stk1160: registers to NTSC like standard Mar 3 19:32:46 home kernel: [122186.590676] stk1160 2-3:1.0: V4L2 device registered as video0 Mar 3 19:32:46 home kernel: [122186.591299] usbcore: registered new interface driver stk1160 Mar 3 19:32:46 home pulseaudio[2312]: [pulseaudio] module-alsa-card.c: Failed to find a working profile.

I would assume(/hope) this is a SAA7113 compatible chip. I actually don't care about audio in my particular application, but there is a Realtek ALC6555 on the bottom as well. Kevin Fitch.
