Drivers Status

PC Card

(32 bit) Card Bus tested, ok. (16 bit) PCMCIA not tested.

FireWire (IEEE 1394)

Modules ohci1394, ieee1394, eth1394 and raw1394 modules loads fine, eth1394 detected as 'eth1' and device /dev/raw1394. Tested with kino and DV-camera - it works.

SD Card reader

Worked out-of-the-box using Kubuntu 7.04 (kernel 2.6.20)

Worked with archlinux (kernel 2.6.30) Loaded modules: sdhci ricoh_mmc

Worked with CentOS 5 (2.6.18), but filenames were all uppercase

Worked better with Fedora 7 (2.6.22)

Worked in Gentoo with ricoh_mmc, (mmc_core), sdhci, and sdhci_pci modules

MemoryStick and xD Picture Card reader

Windows functionality only. There is experimental support for Sony MemoryStick in the latest 2.6 kernels, but not for the Ricoh chipset. No support for xD cards at all.
