Request:

You want to use your Iomega USB Zip 250 Drive with SuSE Linux.

Procedure:

1. switch to user root. The following steps are only important if you´ve SuSE Linux 7.0, in case of newer versions please continue with step 4.

2. Please execute the command lsmod | grep usb You should receive the following output:

   usbcore                42760   0  [usb-uhci]
   usb-uhci               21248   0  (unused) 
or
   usbcore                42760   0  [usb-ohci]
   usb-ohci               21248   0  (unused)

if the displayed output is different from this, load the usb-modules with

   rcusb start

you should receive the following output

   Starting service USB: usb-uhci                          done
or
   Starting service USB: usb-ohci                          done

You can also load the modules manually with


   modprobe usbcore
   modprobe usb-uhci
or
   modprobe usb-ohci

To start the initialization of the usb-system during the bootprozess, edit your /etc/rc.config and set the variable to

   START_USB="yes"
and start
   SuSEconfig

3. Load the module usb-storage with

   modprobe usb-storage
To enable to load the module usb-storage while booting the system edit the file
   /etc/rc.config.d/usb.rc.config

to load the module.


Example:

# # USB_DRIVERS specifies which drivers should be loaded on USB startup # Default is "usb-keyboard mouse". You may additionally specify # acm, usb-serial, ezusb, usb-scsi, printer, hp_scanner, cpia, audio # Please note that not all of those are ready for prime time, yet. # USB_DRIVERS="usb-keyboard mouse usb-storage"

4. Connect the Zip-Drive to a free usb port and check with dmesg if the drive was recognized. It should be displayed as following:

  

USB Mass Storage device found at 2

All external usb-storage-devices are emulated as SCSI-drives, so the device has to be configured as a SCSI-device. The command

   

cat /proc/scsi/scsi

shows a list of all SCSI-devices and all emulated SCSI-devices.
   Example:

   Attached devices: 
   Host: scsi0 Channel: 00 Id: 00 Lun: 00
   Vendor: IBM      Model: DNES-309170W     Rev: SA30
   Type:   Direct-Access                    ANSI SCSI revision: 03
   Host: scsi0 Channel: 00 Id: 06 Lun: 00
   Vendor: TOSHIBA  Model: DVD-ROM SD-M1201 Rev: 1R08
   Type:   CD-ROM                           ANSI SCSI revision: 02
   Host: scsi1 Channel: 00 Id: 00 Lun: 00
   Vendor: IOMEGA   Model: ZIP 250          Rev: 31.G
   Type:   Direct-Access                    ANSI SCSI revision: 02

The Zip drive was emulated as SCSI-device and can be integrated into the system. Please take a look at the order of the Zip-devices in our example. The Iomega Zip250 Drive has to be configured as a second SCSI-hard disk (/dev/sdb) because of the position in the listing and the Direct-Access entry. Most of the Iomega Zip250 drives are formatted for DOS-usage, this means you´ve to mount the disk as the fourth partition of the SCSI-device.

The following command mounts the Zip disk as fourth partition of the second SCSI-device

   

mount /dev/sdb4 /mnt

/mnt provides the removeable disk of the /dev/sdb4 device.
