Unfortunately the sysctl did not change a thing with regard to the =20 Card reader. 3. I added the chip ID and the second device is now recognized as a =20 sdhci device but still does not see any card inserted: Nov 6 16:32:20 NB0117232 kernel: sdhci0: <RICOH R5C822 SD> mem =20 0xe4003000-0xe40030ff irq 19 at device 6.3 on pci2 Nov 6 16:32:20 NB0117232 kernel: sdhci0: 1 slot(s) allocated Nov 6 16:32:20 NB0117232 kernel: sdhci0: [ITHREAD] Nov 6 16:32:20 NB0117232 kernel: sdhci1: <RICOH R5C843 SD> mem =20 0xe4004000-0xe40040ff irq 19 at device 6.4 on pci2 Nov 6 16:32:20 NB0117232 kernel: sdhci1: Hardware doesn't specify =20 base clock frequency.
