 Posted: Sun Aug 08, 2010 3:42 am Post subject: O2 micro card reader |
 |
|
I've got this card reader in my Dell Studio 17 laptop, but I haven't been able to make it work yet. Relevant output of lspci:
| Code: | 14:00.1 SD Host controller [0805]: O2 Micro, Inc. Device [1217:8120] (rev 01)
14:00.2 Mass storage controller [0180]: O2 Micro, Inc. Device [1217:8130] (rev 01) |
The options I have selected in the kernel (2.6.34-r1 x86_64) are:
| Code: | MMC=y
MMC_BLOCK=y
MMC_BLOCK_BOUNCE=y
MMC_SDHCI=y
MMC_SDHCI_PCI=y
|
Everything else MMC not set.
When I insert a memory card in the reader nothing happens at all: nothing in dmesg, no new devices... nothing at all. Any idea what I'm doing wrong? |

So, after almost one full year, I'm still unable to get the card reader to work. The kernel config options are still the same, and still nothing happens when I insert a memory card in the slot.
Help...? |

The O2 Micro SD/MMC Card Reader uses the the kernel's sdhci support.
An example configuration under my 2.6.35 kernel's menuconfig 'Device Drivers > MMC/SD/SDIO card support':
| Code: | [ ] MMC debugging
[ ] Assume MMC/SD cards are non-removable (DANGEROUS)
*** MMC/SD/SDIO Card Drivers ***
<*> 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 ***
<*> Secure Digital Host Controller Interface support
<*> SDHCI support on PCI bus
[ ] Ricoh MMC Controller Disabler (EXPERIMENTAL)
<*> SDHCI support on the platform specific bus
< > Winbond W83L51xD SD/MMC Card Interface support
< > TI Flash Media MMC/SD Interface support (EXPERIMENTAL)
< > MMC/SD driver for Ricoh Bay1Controllers (EXPERIMENTAL)
< > ENE CB710 MMC/SD Interface support
< > VIA SD/MMC Card Reader Driver |
My device: | Code: | 14:00.1 SD Host controller: O2 Micro, Inc. Device 8120 (rev 01) (prog-if 01)
Subsystem: Dell Device 041b
Flags: bus master, fast devsel, latency 0, IRQ 17
Memory at f0e03800 (32-bit, non-prefetchable) [size=256]
Capabilities: [a0] Power Management version 3
Capabilities: [48] MSI: Enable- Count=1/1 Maskable+ 64bit+
Capabilities: [80] Express Endpoint, MSI 00
Capabilities: [100] Virtual Channel
Capabilities: [200] Advanced Error Reporting
Kernel driver in use: sdhci-pci |
Inserting an 8GB SD card into the slot exposes the following output in syslog: | Code: | kernel: [ 160.176423] mmc0: new SDHC card at address e624
kernel: [ 160.176616] mmcblk0: mmc0:e624 SU08G 7.40 GiB
kernel: [ 160.176680] mmcblk0: p1 |
