Have just replayed the upgrade in a VirtualBox VM using a clean install of Ubuntu 18.04.
Before the upgrade (of policy-kit), the braille display works (both output and input). After the upgrade and reboot, the same errors appear in /var/log/syslog: Jul 18 11:49:43 test-VirtualBox brltty[409]: BrlAPI connection fd=27 accepted: local <unnamed> Jul 18 11:49:43 test-VirtualBox brltty[409]: brltty: BrlAPI connection fd=27 accepted: local <unnamed> Jul 18 11:49:43 test-VirtualBox brltty[409]: polkit_authority_check_authorization_sync error 11: Resource temporarily unavailable.
