SGP seems to work w the 50 megapixel Canon 5Dsr but it takes about 1.5 minutes to download each cr2 file. Other programs such as Backyard Eos seem to take considerably less time. Usb cabling was the same. Is this download time normal?
Reset computer bios to defaults and all was fixed.
Interesting. Wonder if USB was in some sort of 1.1 compatibility mode?
