Commerce usps won't get rates Drupal 7, commerce shipping 2.0, and usps shipping method. Configured the product types with weight and dimension physical field. All products have weights and dimensions. All USPS services checked. The username and the connection address are set. The shipping service pane is in the correct sequence in checkout (after shipping info). At shipping services during checkout I get "No shipping rates found for your order. Please continue the checkout process."
I had added the weight and dimension fields to the existing products using defaults. I needed to save each product for these to take effect. Works now.
