Go to the USPS settings page:
Back end -> Store Setup -> Shipping -> U.S.P.S. settings tab

Tick the "Log all communication between shopping cart and USPS server:" option and save the form.

Now X-Cart 5 will log all requests sent to USPS servers and response received from the servers to the "[xc5]/var/log/USPS.log" file.
