I've recently obtained a Sampo Scream Cam DCE-310M. The device is a 3-in-1 USB digital camera/color web cam/MP3 player. I've been trying to figure out how to get it to work fully under Linux. Has anyone had any experiences with this device? >From my observations of how the Windows software operates, the MP3 player and digital camera functionality is accessed by turning the camera on and connecting it to the USB cable. Leaving the camera turned off and connecting it to the USB cable causes it to function as a web cam. When I connect the camera (while turned on) under Linux, the USB subsystem finds a new device, but the hotplug usb agent fails to find a matching entry in the map. >From /proc/bus/usb/devices: T: Bus=01 Lev=01 Prnt=01 Port=01 Cnt=02 Dev#=3D 16 Spd=12 MxCh=3D 0 D: Ver=3D 1.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=3D 8 #Cfgs=3D 1 P: Vendor=0C25 ProdID=0310 Rev=3D 3.00 S: Manufacturer=3DNetChip Technology S: Product=3DNET2888 USB Interface Controller C:* #Ifs=3D 1 Cfg#=3D 1 Atr` MxPwrP0mA I: If#=3D 0 Alt=3D 0 #EPs=3D 4 Cls=FF(vend.)

I believe the device may well function with the usb-storage module, but I need the map entry to test that theory. Interestingly when I connect the camera while turned off, the usb subsystem fails to list the connection of any device at all. Knowing that Windows can see or at least use it when in this state (as a web cam) makes me wonder as to why Linux does not register the connection of the device. I'd like to be able to get it to function as a web cam too, but this makes it very hard to even know where to start. Any help will be greatly appreciated. -- Bob Minowicz ------------------------------------------------------- Enterprise Linux Forum Conference & Expo, June 4-6, 2003, Santa Clara The only event dedicated to issues related to Linux enterprise solutions www.enterpriselinuxforum.com _______________________________________________ Linux-hotplug-devel mailing list http://linux-hotplug.sourceforge.net Linux-hotplug-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linux-hotplug-devel
