Hi all,

How to mount a multi-slot USB flash card reader/writer on Linux ?
I have no problems mounting my camera, which appears as /dev/sda1 vfat partition.

But when I plug in that multi-slot device, it is recognized and mapped by usb-storage to /dev/sda, but
then I can do nothing ... there should be 2 disks (as Windows recognizes), but how to mount them ??

The device is DataFab SD/CF reader/writer DTCFSD-USBD,
Linux RH 7.3 with kernel 2.4.20.

Thanks for any hint !
Cheers
        Andrei
