I've added this to my own linux/drivers/media/usb/em28xx/em28xx-cards.c: { USB_DEVICE(0xeb1a, 0x2885), /* MSI Digivox Trio */ .driver_info = EM2884_BOARD_TERRATEC_H5 }, So it would load automatically. I've been using two of these with tvheadend. So can this device be added? Any more info needed? Best regards, P. van Gaans
