After upgrading from Alpha 8, where all shipping rate quotes were working properly, I too found that I wasn't getting any USPS rate quotes.
I traced problem with USPS shipping quotes not returning any quotes to this piece of code (bazaar version 728 of uc_usps.module):
<?php
if ($service != 'data' || !in_array($service, $usps_services)){
unset($services[$service]);
}
?>This condition will always evaluate to TRUE, since $service is never = 'data'. The result is that no rate quotes will be returned from the USPS module.
Changing the above lines to:
<?php
if (!in_array($service, $usps_services)){
unset($services[$service]);
}
?>fixes the problem.
