There doesn't seem to be anything available for download on https://launchpad.net/ubuntu/+source/linux/3.10.0-3.12. I randomly tried https://launchpad.net/ubuntu/+source/linux/3.10.0-5.14 but couldn't find any .debs there either. Are you sure these links are working?
I believe there were some important upstream fixes for the udl driver in (upstream) 3.11, so I would not expect any Ubuntu kernels to work that were based on upstream < 3.11. So maybe things got broken right away on the rebase?
