I have a Dell XPS M1210 and I can confirm that this has been an issue at least since Dapper (6.06).
In the past I solved it by replacing the kernel with a custom kernel with the only difference being that MMC is not dynamically loaded (as a module) but built into the kernel. The weird thing is that sporadically, an inserted card would be detected and mounted ... no clue as to why it doesn't work every time. Of course the card reader is fully functional in Windows XP. lspci 03:01.1 Generic system peripheral [0805]: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 19) 03:01.2 System peripheral: Ricoh Co Ltd Unknown device 0843 (rev 01) 03:01.3 System peripheral: Ricoh Co Ltd R5C592 Memory Stick Bus Host Adapter (rev 0a) 03:01.4 System peripheral: Ricoh Co Ltd xD-Picture Card Controller (rev 05) -- Feisty - Dell SD Card Reader Now Broken https://bugs.launchpad.net/bugs/105773 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
