It doesn't make a lot of sense that your cart reads: Weight: 2.22lbs

and the USPS module is reading: (0 lbs, 1 oz)

What other shipping modules are installed?

I would try doing:

1 Remove USPS

2 Reload the files from a clean Download

3 Install USPS

4 Configure USPS

and see if that fixes the problem ...

If not, set the debug to Logs and test the shipping, then, look in your /logs directory and post the Log file that is being created ...
