I bought my wife a D-380 for her recent trip to VA. Today I downloaded the 59 pictures she took. This was the first time to be connected to my XP machine. I went outside and took some pictures and came back in and tried to download mine and I get the "device not ready" message. What I noticed is the USB "sound" when you plug it in is flat sounding. I tried another USB device and it works (and sounds) correct. What am I doing wrong?
