Hi, I recently bought an Elro DVR14 set in a sale. I plugged in Ubuntu Linux 12.10 with recent updates and noticed the following in dmesg: [ 3339.600316] usb 2-1: new high-speed USB device number 7 using ehci_hcd [ 3339.736181] usb 2-1: New USB device found, idVendor=0572, idProduct=58a6 [ 3339.736192] usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 3339.736200] usb 2-1: Product: Polaris AV Capture [ 3339.736207] usb 2-1: Manufacturer: Conexant Corporation [ 3339.736213] usb 2-1: SerialNumber: 0000000002 [ 3339.741425] cx231xx #0: New device Conexant Corporation Polaris AV Capture @ 480 Mbps (0572:58a6) with 6 interfaces [ 3339.741433] cx231xx #0: registering interface 1 [ 3339.741551] cx231xx #0: can't change interface 4 alt no. to 3: Max.

Any help is appreciated. By the way, the Windows driver I use is the one that does not have Windows_XP added to it. That one seems to be for a 3104 or something device. Thanks for any help!
