Yeah, I saw your posting from August 19th. When/where did you buy your box? Maybe a difference in firmware? Could you send me your "lsusb -v" output as a text file? Would like to do a side by side diff with mine. "uvccapture" behaves the same here. Insists on the 1984x1328 resolution. The aspect ratio of your device is 4:3. Pretty far away from the expected 3:2 for a 36x24 mm slide. On the other side, the aspect ration of my device is 1.494, which is close, but odd. > uvccapture).

Please see the respective file from my "other os" installation. CropSize1 still indicates a sensor size of 1984x1328, but different from yours. Both crop areas at least have the expected aspect ratio. My version of MediaImpression is 1.2.27.515. The comment about the advertised resolution might be right. Especially as they talk about "optical resolution" - whatever that means. <?xml version="1.0" encoding="UTF-8" ?> - <Profile> - <ImageFormate> <Type Extention="JPG" Support="1" /> <Type Extention="BMP" Support="0" /> <Type Extention="PNG" Support="0" /> <Type Extention="PCX" Support="0" /> <Type Extention="TIF" Support="1" /> <Type Extention="TGA" Support="0" /> </ImageFormate> <CropSize1 XValue="1950" YValue="1300" /> <CropSize2 XValue="918" YValue="702" /> <CropOffset XValue="0" YValue="0" /> <AutoEnhance Support="1" /> <AutoColorBalance Support="1" /> <SalixPID Value="3100" /> <SalixVID Value="115B" /> <SalixDeviceName Value="USB Scanner" /> <SlideWhiteBalance135 Value="3000" /> <NegativeWhiteBalance135 Value="5000" /> <BWNegativeWhiteBalance135 Value="6000" /> <NegativeWhiteBalance110 Value="4000" /> <BWNegativeWhiteBalance110 Value="4000" /> </Profile> Cheers Martin _______________________________________________ Linux-uvc-devel mailing list [email protected] https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
