  • Interface: PCI Bus
  • Functions:
    • PC-Card Controller: PCI 1180:0476
    • FireWire 400 (IEEE 1394a): 1180:0832
    • 4-in-1 card host: PCI 1180:0822

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 Card reader

It was developed by Maxim Levitsky and it should work on all notebook with Ricoh R5C592 MS. Download archive, unpack and in terminal in unpacked folder type make;sudo make install;sudo make load

xD Picture Card reader

Windows functionality only. No support for xD cards at all.

Problems

  • Some microSD-to-SD adapters can lead to serious problems reading your microSD card. In such a case a normal SD card will be detected instantly but the adapter with the microSD card will fail to be recognized. The syslog (take a look with $ tail -f /var/log/syslog while inserting the card) will only show this line: mmc0: error -110 whilst initialising SD card. This issue is caused by a bad electrical connection, pulling the adapter out a little will solve this in most cases. Permanent fix: use a better adapter.
