I can't access it as a device. lsusb gives idVendor 0x2770 and idProduct 
0x9120. I tried gragging the picture from the DigiKam window, but I get a 
corrupted file (32 Bytes) that contains only the name of the picture 
(pict003.ppm.. which does not bring us further ;( )

I'll search my old old old CDs to see if I can find the original Windows 
software, out of curiosity to know what picture format we have there...

It would mainly be interresting to find out what leads DigiKam to choose 4GB 
as a size. I suppose it comes from the fact that DigiKam has to relie on the 
picture file to tell it' size. But why suppose it's 4GB?
