The Zling Photo Wallet is a 5 GB USB Storage Device with Card Reader.
Zling says, it works with linux, but doesn't say how.
The first two, i got, were broken. So i didn't know if i was wrong or the drives.
Don't be confused, that fdisk shows a curios partition tbale for the hard drive.

So, how to recognize, if it works fine and how to handle it?
The Kernel needs the following parameters set

CONFIG_SCSI
CONFIG_BLK_DEV_SD
CONFIG_CHR_DEV_SG
CONFIG_SCSI_MULTI_LUN

CONFIG_USB
CONFIG_USB_STORAGE
CONFIG_USB_DEVICEFS
CONFIG_USB_EHCI_HCD
CONFIG_USB_UHCI_HCD
CONFIG_USB_STORAGE

BLK_DEV_UB must not be set.

If dmesg points out something like:

 usb 4-4: new high speed USB device using ehci_hcd and address 3
 scsi1 : SCSI emulation for USB Mass Storage devices
 usb-storage: device found at 3
 usb-storage: waiting for device to settle before scanning

 Attached scsi removable disk sda at scsi1, channel 0, id 0, lun 0
 Attached scsi generic sg0 at scsi1, channel 0, id 0, lun 0,  type 0
 usb-storage: device scan complete

then you probably have not set CONFIG_SCSI_MULTI_LUN 

Anyway, in this case, the hard drive can be accesed by mounting /dev/sda (without partitition number)

If CONFIG_SCSI_MULTI_LUN is set, dmesg points out something like:

 sb 4-4: new high speed USB device using ehci_hcd and address 7
 scsi6 : SCSI emulation for USB Mass Storage devices
 usb-storage: device found at 7

Just mount /dev/sdb1 (CF) or /dev/sdc1 (SD/MM) to access cards that are pluged into the Card Reader.
