Hi, I posted this info to the linux-media list recently, but thought it might be worth reporting here too. It seems two different products made by Pinnacle Systems use the same USB ID, 2304:0212. (From the Windows driver INF files, there may be another two pairs of products with duplicate IDs, see below. Sigh.) The usb.ids file entry for 2304:0212 is for "Studio PCTV USB (NTSC)". That's an old USB 1.x TV tuner/capture device from circa 2000. However, the Pinnacle 700-USB video capture device has the same ID. The result is that when a 700-USB is connected, Linux thinks it's a PCTV USB and tries (incorrectly) to use the usbvision driver. Did Pinnacle release two different products with the same USB VID:PID? Or perhaps there are entries in pctvusb2.inf for products which were never actually released, so the IDs were reassigned to later products? If anyone has an original PCTV USB with VID:PID 2304:0212, please let me know. Maybe Pinnacle figured it was okay to recycle USB IDs, since the PCTV USB is only supported up to Windows 2000, the 700-USB in XP and later. If you want to compare the IDs given in the Windows driver INF files, Windows drivers for the 700-USB are available from http://cdn.pinnaclesys.com/SupportFiles/Hardware_Installer/readmeHW10.htm or direct URLs http://cdn.pinnaclesys.com/SupportFiles/Hardware_Installer/PCLEUSB2x32.exe http://cdn.pinnaclesys.com/SupportFiles/Hardware_Installer/Pinnacle_Video_Driver_64bit.exe Looking at the INF file for the 700-USB driver (MarvinAVS.inf): [Marvin.Device] %Marvin.DeviceDesc%=Marvin.Install,USB\VID_2304&PID_0206 ;Marvin-classic %MarvinCR.DeviceDesc%=MarvinCR.Install,USB\VID_2304&PID_0212 ;Marvin-CR %MarvinLite.DeviceDesc%=MarvinLite.Install,USB\VID_2304&PID_0213 ;Marvin-Lite %Marvin510.DeviceDesc%=Marvin510.Install,USB\VID_2304&PID_0223 ;Marvin-510 %Marvin710.DeviceDesc%=Marvin710.Install,USB\VID_2304&PID_0224 ;Marvin-710 Windows drivers for the old PCTV USB can be downloaded from ftp://ftp.pinnaclesys.de/driver/pc/tvusb/PCTVUSBW2K104.exe (Warning: large file!) Download and unpack that, check pctvusb2.inf. (The "usb2" in the name doesn't refer to USB 2.0.) An excerpt: %P0211.DeviceDesc% = P0211.Install,USB\VID_2304&PID_0211 ;PAL, R,P %P0212.DeviceDesc% = P0212.Install,USB\VID_2304&PID_0212 ;NTSC, R,T %P0213.DeviceDesc% = P0213.Install,USB\VID_2304&PID_0213 ;NTSC, R,P %P0214.DeviceDesc% = P0214.Install,USB\VID_2304&PID_0214 ;PAL I, R,T So the "Marvin-Lite" also has a duplicated VID:PID. Marvin-Lite must be the 500-USB capture device, and is listed correctly in usb.ids. There's another duplicated entry in MarvinPro.inf. This for the USB breakout box supplied with Pinnacle/Avid Liquid Pro (similar to the 700-USB but with 5.1 audio and component video in/out): %Marvin.DeviceDesc%=Marvin.Install,USB\VID_2304&PID_0211 ; FX2 MarvinDiscrete Pro Rev. 0.1 -- Mark -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
