Asked by Vlad Alekseev

I have Uniwill 258KA laptop. There're the PCMCIA devices: O2Micro OZ711Mx MemoryCardBus Accelerator and two OZ711M1MemoryCardBus Controller in Device Manager.

There's one PCMCIA slot and one SD/MMC/MS-slot. When i insterting a card Ubuntu does not detect it.
I didn't tried inserting any PCMCIA card because i haven't it.
I would like to get help to make my cardreader working.

Vlad-

My laptop, a Gateway model, also has a built in card reader. Unfortunately, it doesn't work.

I have a cheap, $12, USB 2.0 Kodak 6 in 1 card reader that is detected and works just fine.

2.6.18 kernel now supports a bigger number of devices. You could try if yours is supported too.

The card reader is not supported by 2.6.18 kernel atm, as it does not understand sdhci, according to http://mmc.drzeus.cx/wiki/Controllers/O2/OZ711Mx

I am interested in teh topic. Do you know who is working on the sdhci part of the kernel code and who is working on the
  O2Micro_PCMCIA_SCR_203_Linux_Kernel26_OpenSource.tar.gz
package.

I will try to contact them because it seems that the kernel part has dramatically changed, so the O2Micro Code is not compiling any more.
I still installed the pcmciautils-014 and I see following:

  # pccardctl ident
   Socket 0:
     no product info available
   Socket 1:
     product info: "O2Micro", "MemoryCardBus ATA", "V1.1", ""
     manfid: 0xffff, 0x0001
     function: 4 (fixed disk)

 #pccardctl info
   PRODID_1=""
   PRODID_2=""
   PRODID_3=""
   PRODID_4=""
   MANFID=0000,0000
   FUNCID=255
   PRODID_1="O2Micro"
   PRODID_2="MemoryCardBus ATA"
   PRODID_3="V1.1"
   PRODID_4=""
   MANFID=ffff,0001
   FUNCID=4

Can you help with this problem?
