Then consider yourself very lucky - some laptop manufacturers play nice and the card reader identifies itself, and works as, a USB mass storage device; so it works out of the box with no extra drivers needed for either the card reader, or the flash memory card. The Texas Instruments chip/ card reader that Alex's work here is currently aimed at does not - it has a completely proprietary, so called "FlashMedia" chip/ interface that talks to MMC/ SD, MemoryStick (/ Pro), and SmartMedia/ xD cards, of which TI have refused to release any specs. Yes, this chip doesn't even use sdhci for communicating with MMC/ SD cards - tifm_sd (Alex's previous work on the MMC/ SD front for this TI chip) handles that. MemoryStick support is more complicated in this case than MMC/ SD, given that on top of TI refusing to release specs for their own FlashMedia chips, Sony will also not release any specs on MemoryStick cards; the same is also true of xD with Olympus and Fuji. -Carlos -- E-Mail: [EMAIL PROTECTED] Web: strangeworlds.co.uk GPG Key ID: 0x23EE722D -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
