Using Sony Clie PEG NR70V as a Memory-Stick Reader under Linux

Make sure appropriate Kernel and modules are installed: You will need usbserial, usb_storage, usbcore, sg and scsi_mod( #lsmod). Start the MS-import utility on the Clié. Check If Clié was detected as scsi device ( #cat /proc/scsi/scsi). If not, leave MS-Import running and turn off the Clié and swich on again. This is because the MS-Imprort starts too slow to be recoginiszed by Linux as scsi device sometimes. If the Sony was detected as a scsi device you can just mount it.

I reacently tried to install the card reading option of my sony clie nr70V so that it workes for linux. I was amazed as I realized, that linux has native support for the card reading option of the sony clie.
What I did was the following:
Just plug the sony into the craddle which is connected to some USB port of the linux box. Then turn on the clie and run MS-import on the sony. Than linxux shoud automatically detect the PDA as a USB mass storage device and mount it if you have hotplugging functionallity installed.
But on my device it didnt work. Then I Googled a bit and found out that a lot of users had the same problem, althogh the have the appropriate Kernel and modules installed ( You will need usbserial, usb_storage, usbcore, sg and scsi_mod)
but I couldnt find the solution.
Then I checked /var/log/messages. It reads:
-snip-

Feb 17 21:35:59 linux kernel: USB Mass Storage device found at 4
-snip-

So the device was recognized but it was not installed as a scsi device (Generic scsi - sg module)
# cat /proc/scsi/scsi revealed no entries. This probalbly means the USB device is recognized but scsi support is not installed. Actually I never figured out why, yet I found a work around.

What I did was the following:

Start and Leave MS-Import running on the palm while connected to the PC. Turn off the palm.

kernel messages:

Then turn on the palm again, e voila:

And a window opend on by KDE by whichcraft which revealed all the contents of the memory stick of my Sony Clie. Good!
