7-in-1 Card Reader recognized in kernel but not media

[sonix]

So I have that Hewlett Packard 7-in-1 Card Reader. I looked up a couple posts here of others who have multiple card reader and followed with what they did (enabling LUP, usb-storage in kernel).

So I dmesg when i stick a card in and no update to dmesg. but a blue LED lights up next to the card.

here's whats in dmesg though.

I have two of these type devices and it is far from 100%
1 supports the 7 or so types it can handle perfectly, but doesn't automate mounts using udev/dbus/pmount .
The other works for all types except SD, (dmesg shows nothing), but mounts all the other types perfectly.

So I don't think its just kernel support, I think so devices might be a little "flakier" than others.

Make sure you enable 'probe all luns' in the kernel config (under scsi), and there are new MMC / SD options available in the kernel (towards the bottom of device drivers iirc), enable that as well.

Make sure that you have disabled then USB block driver (BLK_DEV_UB) in the kernel since it causes a conflict.
Explore /dev/ for nodes (are you using udev?)
udevinfo -a -p $(udevinfo -q path -n /dev/sda)
is the magic command to see what is behind the different /dev nodes. If it would work you would see for each slot a device. e.g /dev/sda, /dev/sdb, ...
If you have /dev/uda then the above USB block driver (BLK_DEV_UB) is on.

udevinfo -a -p $(udevinfo -q path -n /dev/mmcsd)
is as I said the magic command that I was looking for long time.
udevinfo -q path -n /dev/mmcsd
tells you where under /sys the kernel has put the data about my multimedia card / secure disk slot of my multi card reader.
/block/sdc
Knowing where the kernel has put the data under /sys you could do a
udevinfo -a -p /block/sdc
And I would get the information about all of it. Special interest would be:
It is USB2 full speed! DRIVER=="ehci_hcd"
Sits in my SYSFS{product}=="USB2.0 Card Reader"
Here one of the key options in the kernel configuration DRIVER=="usb-storage"
Here is the name of the slot in the multi readerSYSFS{model}=="IC1210 MMC/SD"

Instead of the two commands the magic command just puts the result of the first command as parameter for the second command.


The problem of the multi slot card readers is to find out what /dev/sd* is mapped to what slot? The sample above tells how to find it out. To scare you, the mapping is not static, if you plug in other memory sticks it could produce an other mapping (as windows does).

Way out are udev rules. Edit /etc/udev/rules.d/10-local.rules
#Apacer Card Reader
BUS="scsi", KERNEL="sd*", SYSFS{model}=="IC1210 CF", NAME="cflash%n"
BUS="scsi", KERNEL="sd*", SYSFS{model}=="IC1210 MS", NAME="mstick%n"
BUS="scsi", KERNEL="sd*", SYSFS{model}=="IC1210 MMC/SD", NAME="mmcsd%n"
BUS="scsi", KERNEL="sd*", SYSFS{model}=="IC1210 SM", NAME="smedia%n"
#any further usb memory stick
BUS="usb", DRIVER=="usb-storage", KERNEL="sd*", NAME="usbstk%n"
and you have it fixed. This is also where my /dev/mmcsd comes from.
All usb memory sticks plugged in can be accessed under /dev/usbstk and not one time sda then sde and so on.
it took me a long time until my computer behaves like this, but it is not that complicated when you know how.

should i create that file or could i add this to /etc/udev/rules.d/50-udev.rules ?

[lindegur]

By the way happy new year, at least here its 2006

Dont't edit /etc/udev/rules.d/50-udev.rules since it will go lost after some udev update. Create the /etc/udev/rules.d/10-local.rules it will have priority and if no rules match then udev looks in /etc/udev/rules.d/50-udev.rules

If I look at your responsel I would say that you should be able to do mount /dev/sde for your MS (memory stick) and sdc CF (compact flash). I recommend to do first a simple mount and then adapt the udev rules. Can you do a mount?

What I don't like is couldn't open device directory I get much more output from the udevinfo -a -p $(udevinfo -q path -n /dev/sde) as a block with DRIVER=="usb-storage"
and an other with SYSFS{product}=="USB2.0 Card Reader" and an other SYSFS{product}=="EHCI Host Controller" so much data that I dont want to copy all of it here. I think something is wrong there, maybe with the kernel? udevinfo goes up to /sys/devices/pci0000:00' in my case and prints out all in this directory tree. However in your case it stops. Can you check manually with konqueror what is there? (I have to admit that I'm still a newbe if it comes to those detail but I like to learn).

Some thing simple to begin:
Can you mount other usb devices as a simple usb memory stick plugged in directly to one of the computers usb connectors?
In the console type su then password and do a mount /dev/sde1 /mnt/somedirectory . Remember do it as root and the 1 means first partition on the memory stick in this case.

EDIT: Resolved to my liking. Follow link below, to other thread, for my solution.

Bumping this tread.

I am close to getting the multi reader on my Dell 2405fpw working. For whatever reason, it (udev) will not create symlinks based on my rules unless I "hotplug" the reader/monitor with a CF already inserted. If I insert/remove a CF any other time, nothing happens, nothing changes. Ideas?
