I actually thought for a while that it might not be supported, because it wasn't obvious that I needed to set the appropriate V4L settings, which weren't defaulted to the ones I need (NTSC, composite video input), or even which program I should start testing with. So it looks like I should make sure that the documentation on linuxtv.org gets improved. My first successful test occurred with MPlayer: mplayer tv:// -tv device=/dev/video1:input=1:normid=0 (my webcam is /dev/video0, so the USB stick gets /dev/video1) I'm wondering about firmware, though, because I notice that the Windows drivers include a firmware file (merlinFW.rom, 16382 bytes, md5sum 647d818c6fc82f385ebfbbd4fb2def6d), and the video looks slightly cleaner in Windows-- this might be accomplished with a software filter, but I thought it might be possible that it's being done by firmware. Does the em28xx driver load a firmware? Also, any firmware that gets loaded only persists until the device is unplugged, right? And so my prior successful test on Windows has nothing to do with my later success on Linux... just want to be sure about that. I also tried testing with Windows in Virtualbox, but had no luck-- does anyone know if this should be possible? (I can provide more info about my virtualbox testing if anyone's interested.) Finally, lsusb output: Bus 002 Device 004: ID eb1a:2860 eMPIA Technology, Inc. (let me know if you want the verbose output) And dmesg output: usb 2-1.2: new high speed USB device using ehci_hcd and address 4 usb 2-1.2: configuration #1 chosen from 1 choice em28xx: New device @ 480 Mbps (eb1a:2860, interface 0, class 0) em28xx #0: chip ID is em2860 em28xx #0: board has no eeprom em28xx #0: Identified as Unknown EM2750/28xx video grabber (card=1) em28xx #0: found i2c device @ 0x4a [saa7113h] em28xx #0: Your board has no unique USB ID. em28xx #0: A hint were successfully done, based on i2c devicelist hash. em28xx #0: This method is not 100% failproof. em28xx #0: If the board were missdetected, please email this log to: em28xx #0: V4L Mailing List em28xx #0: Board detected as EM2860/SAA711X Reference Design em28xx #0: Registering snapshot button... input: em28xx snapshot button as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/input/input10 saa7115 8-0025: saa7113 found (1f7113d0e100000) @ 0x4a (em28xx #0) em28xx #0: Config register raw data: 0x00 em28xx #0: v4l2 driver version 0.1.2 em28xx #0: V4L2 video device registered as /dev/video1 em28xx #0: V4L2 VBI device registered as /dev/vbi0 usbcore: registered new interface driver em28xx em28xx driver loaded I guess the part about the snapshot button means that I can use the push button on the USB stick to trigger stuff if I want (yay!), but I have no idea how to make that actually happen. I'll be happy to provide more info if needed. I really appreciate the great work that's been done on the V4L drivers! Ivan
