In this case: 1) SD card reader is PCI device, not USB device: lspci ... 03:01.2 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 21) (prog-if 01) ... AFAIK, it needs SDHCI PCI driver. 2) Similarly as smart card reader, SD reader is also usually not recognized by BIOS (it is not possible to boot from this device - at least on my notebook - but I did not check if there exists some BIOS settings which can enable another behavior).
