Dear Silvia,
I have personally used a Dino-Lite USB microscope for both insect identification as well as for general examination when doing fieldwork in Egypt and I thought it was a great instrument. I will have to do a little research in my reports to find out what model it was. I have also contacted the lab at the Arizona State Museum; they use a USB microscope for their IPM program that I remember worked quite well.
Also, here is a link to some smartphone-compatible microscope options

I'll work on getting those Dino-Lite specs for you!
