A web search shows some similar reports (e.g. <https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1329566>, <http://askubuntu.com/questions/473848/ubuntu-14-04-realtek-semiconductor-co-ltd-rts5227-pci-express-card-reader-isn>). But in that last one, it turns out that the out-of-tree driver does work. Is there anything Philipp can do (e.g. debugging options) to help get this fixed?
