 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.

 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.
