 |
|
Hi,
My laptop has a built-in SD card reader. When I insert a card I see the following in the system logs:
| Code: | Apr 15 19:37:18 lapself kernel: usb 2-6: new high-speed USB device number 3 using ehci_hcd
Apr 15 19:37:18 lapself kernel: usb 2-6: New USB device found, idVendor=05ca, idProduct=1880
Apr 15 19:37:18 lapself kernel: usb 2-6: New USB device strings: Mfr=1, Product=2, SerialNumber=3
Apr 15 19:37:18 lapself kernel: usb 2-6: Product: USB2.0-FLASH Media
Apr 15 19:37:18 lapself kernel: usb 2-6: Manufacturer: RICOH
Apr 15 19:37:18 lapself kernel: usb 2-6: SerialNumber: R5U880-00003

However, I don't think any new /dev is created, and I'm not sure how to mount this. It would be even better if the system auto mounted it. How can this be done?
Thank you.

oneself,
I noticed that ricoh had kernel config settings - not sure if you have them set or if they're for your device or not.
CONFIG_MMC_RICOH_MMC
CONFIG_MMC_SDRICOH_CS
mount will show if it's mounted.

Hi, thank you for your reply,
I've added those modules but it doesn't seem to change anything.

From what I read around, this thing should work out-of-the-box. It's an USB device, so the cards should show up as regular disks, like usb-sticks do. So /dev/sdb, /dev/sdc or similar.
Have you tried other distros? If it works on them, it's a kernel config issue. BillWho's MULTI_LUN advice is very good in this regard, make sure you have that. |

| memory cards typically show up as /dev/mmc* devices (at least on card readers I've used so far). |

Yes, with PCI card-readers. But this is an USB card-reader. Cards don't show up as, well, cards, but as mass storage devices. |

So, does that mean that they should show up as /dav/sd*?
Will the /dev be created automatically or do you need to create it manually?
Is this just a kernel issue still?

If I plug in my USB card reader, and load it with a card, I get a complaint "Only root can mount
/dev/sda1 on /media/usb", since I have permissions set wrong. If I then mount the card as root
it looks like an ordinary file-system.
I don't have any special drivers in the kernel - just USB_STORAGE and USB_LIBUSUAL,
and the UHCI / OHCI / EHCI drivers. I don't think LIBUSUAL is necessary, since I don't
have any of the specific drivers configured; and I don't have MULTI_LUN set.

MULTI_LUN is required for card readers that support more than one card type or you only get LUN 0, whatever that happens to be.

I was missing:
| Code: | | CONFIG_USB_STORAGE=m |
Thank you all.
