I've just checked the example with my D5200 and it works as it should. It's hard to belive D90 doesn't support fundamental feature such as capture-image-and-download while it's listed on gphoto's "Supported camera" page with all features support. What's more when I started playing with gphoto I was using D40 which is older than D90 and I didn't experience any problems with it. I remember D40 had a really nice feature which was internal RAM - you could take a photo w/o a SD card so capture-and-download transfer was really fast (for D5200 it takes ca. 4 seconds). You could switch between "Internal" and "SD card" options in the camera menu or via gphoto config. I think "PTP busy" error occured when SD card was selected for storage but the card was missing or was full. I guess D90 is also the generation with internal memory so start with checking if your SD card is ok or switch to internal storage and try the example again.
