CardReader on my notebook (RL5c476)

Hi,

I have spent the last weeks building a LFS-system on my notebook. So far, I like it a lot but there are some things that I couldn't get to work (yet) ;-)

One of these is my CardReader. Whenever I put a card in it, just nothing happens.
Google only confused me even more, telling me that the CardReader does work, that there is no dirver for it,...

The Notebook is a Samsung XVM1500 and according to lspci, it has got a "Ricoh RL5c476 II (rev ac)" controller:

Code:

02:01.1 CardBus bridge: Ricoh Co Ltd RL5c476 II (rev ac)
        Subsystem: Samsung Electronics Co Ltd: Unknown device c00c
        Flags: bus master, medium devsel, latency 168, IRQ 11
        Memory at 20002000 (32-bit, non-prefetchable) [size=4K]
        Bus: primary=02, secondary=07, subordinate=0a, sec-latency=176
        Memory window 0: 20c00000-20fff000 (prefetchable)
        Memory window 1: 21000000-213ff000
        I/O window 0: 00004c00-00004cff
        I/O window 1: 00005000-000050ff
        16-bit legacy interface ports at 0001

and I am using linux-2.6.11.7.

Can you tell me HOW I can make it work (what kernel requirements are there, what's the driver I need,...) or at least IF it works with Linux at all, please?

Thanx a lot,
Christoph ;-)

I don't really know for sure but my guess is that it there is no full support for it at the moment. It seems to be a solution similar to the Texas Instruments PCI1620 PCMCIA/Cardbus kit that also has a piggyback card reader (like the 5-in-1 readers on Compaq/HP R3000 series laptops). This TI device requires a special firmware in order for the card reader to work - the firmware uploader works just fine, but it requires unencrypted firmware. This firmware is not available in its unencrypted form (the Windows driverr takes care of decrypting the firmware and uploading it to the device).
