Ciao,
stavo cercando di far funzionare il lettore di schede SD sul notebook (asus) ma ho un problemino, quando configuro il kernel nel seguente modo:
Quote:
Device Drivers --->
<*> MMC/SD card support --->
-*- MMC/SD card support
<*> MMC block device driver
[*] Use bounce buffer for simple hosts
preso da qui
il lettore SD funziona perfettamente ma il touchpad non risponde piu' ai comandi 8O, per farlo tornare in vita ho dovuto rimuovere dal kernel quei settaggi..possibile che non posso avere funzionanti entrambi (touchpad e lettore SD) ?

ps. per il touchpad uso hal

lspci del lettore SD
Code:
09:01.0 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller (rev 05)
09:01.1 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 22)
09:01.2 System peripheral: Ricoh Co Ltd R5C843 MMC Host Controller (rev 12)
09:01.3 System peripheral: Ricoh Co Ltd R5C592 Memory Stick Bus Host Adapter (rev 12)
09:01.4 System peripheral: Ricoh Co Ltd xD-Picture Card Controller (rev 12)


grazie in anticipo

ok dopo un po' di tentativi ho notato che il problema era dovuto a
Quote:
[*] Use bounce buffer for simple hosts

quindi l'ho disabilitato ed ho aggiunto i seguenti moduli:

Quote:
<M> MMC block device driver │ │
│ │ [ ] Use bounce buffer for simple hosts │ │
│ │ < > SDIO UART/GPS class support │ │
│ │ < > MMC host test driver │ │
│ │ *** MMC/SD/SDIO Host Controller Drivers *** │ │
│ │ <M> Secure Digital Host Controller Interface support │ │
│ │ <M> SDHCI support on PCI bus │ │
│ │ < > Ricoh MMC Controller Disabler (EXPERIMENTAL) │ │
│ │ < > Winbond W83L51xD SD/MMC Card Interface support │ │
│ │ < > TI Flash Media MMC/SD Interface support (EXPERIMENTAL) │ │
│ │ < > MMC/SD driver for Ricoh Bay1Controllers (EXPERIMENTAL) │ │
│ │

infine:
Code:
echo "mmc_block" >> /etc/modules.autoload.d/kernel-2.6


ora funziona tutto correttamente, spero possa servire :roll:
