    Accesso a pendrive Slackware 9.1

    Ciao a tutti, come si fa a montare e ad accedere ad una pendrive Usb in Slackware 9.1? Mi piacerebbe anche sapere come fare a visualizzare tutto l'hardware presente (in Redhat c'era il browser hardware) sul mio computer.

    ==========================
    How to read this few lines
    ==========================

    These few lines are provided AS IS, no warranty for your hardware

    If the line starts with a "#" you have to execute the command as root;
    if the line starts with a "$" you can execute the command as normal user.

    Examples of shell output are provided by my linux-box configured as is:
    - Slackware 9.0;
    - kernel 2.4.20 (default installation);
    - mainboard ECS K7VZA with 2 USB ports;
    - PCI USB hub with 2 USB ports;
    - pendrive Picodisk Tech 2.


    ===============
    A) Requirements
    ===============

    - A new USB pendrive ready to be plugged into your linux-box;
    - linux kernel >= 2.4.x (older ones do not support USB devices);
    - a mainboard with at least 1 USB port.


    ========================
    B) Finding your pendrive
    ========================

    1) NB: if your distro is one of the latest, you'll probably won't to do this,
    because hotplug will do it for you! Anyway, you can use this step to control
    your configuration and better learn the usage of modules
    Do NOT initially plug in your pendrive! Execute from shell:
    # lsmod
    and load this modules if they aren't listed:
    # modprobe usbcore
    # modprobe uhci
    # modprobe usb-ohci
    # modprobe usb-storage

    2) Check your configuration BEFORE using the new device; USB mass storages are
    recognized by linux as scsi devices, so you'll probably find it as one of
    those, depending on your scsi configuration:
    # cat /proc/scsi/scsi
    You'll read something like this:
    Attached devices:
    Host: scsi0 Channel: 00 Id: 00 Lun: 00
    Vendor: SAMSUNG Model: CD-ROM SC-152L Rev: LS01
    Type: CD-ROM ANSI SCSI revision: 02
    Host: scsi0 Channel: 00 Id: 01 Lun: 00
    Vendor: PHILIPS Model: PCRW804 Rev: 2.0
    Type: CD-ROM ANSI SCSI revision: 02
    and then:
    # lsusb
    with something like this:
    Duplicate HUT Usage Spec at line 2650
    Bus 003 Device 001: ID 0000:0000 Virtual Hub
    Bus 002 Device 001: ID 0000:0000 Virtual Hub
    Bus 002 Device 002: ID 0483:7554 SGS Thomson Microelectronics 56k SoftModem
    Bus 001 Device 001: ID 0000:0000 Virtual Hub
    Bus 001 Device 002: ID 0461:4d03 Primax Electronics Kensington Mouse-in-a-box

    3) Now you can insert your new pendrive into USB port and try to find where the
    pendrive has been attached by the kernel; execute again:
    # cat /proc/scsi/scsi
    and find the differences between now and before: if you can find a new device
    in the list, your pendrive is alive! This time output could be:
    Attached devices:
    Host: scsi0 Channel: 00 Id: 00 Lun: 00
    Vendor: SAMSUNG Model: CD-ROM SC-152L Rev: LS01
    Type: CD-ROM ANSI SCSI revision: 02
    Host: scsi0 Channel: 00 Id: 01 Lun: 00
    Vendor: PHILIPS Model: PCRW804 Rev: 2.0
    Type: CD-ROM ANSI SCSI revision: 02
    Host: scsi1 Channel: 00 Id: 00 Lun: 00 } HERE!
    Vendor: Eutron Model: Picodisk Tech 2 Rev: 1.00 } HERE!
    Type: Direct-Access ANSI SCSI revision: 02 } HERE!
    and then:
    # lsusb
    with something like this:
    Duplicate HUT Usage Spec at line 2650
    Bus 003 Device 001: ID 0000:0000 Virtual Hub
    Bus 002 Device 001: ID 0000:0000 Virtual Hub
    Bus 002 Device 002: ID 0483:7554 SGS Thomson Microelectronics 56k SoftModem
    Bus 001 Device 001: ID 0000:0000 Virtual Hub
    Bus 001 Device 003: ID 073d:0050 } HERE!
    Bus 001 Device 002: ID 0461:4d03 Primax Electronics Kensington Mouse-in-a-box
    it's again your pendrive

    4) At this point you're ready to find where your pendrive has been attached;
    # dmesg | more
    will give you an idea:
    hub.c: new USB device 00:0a.0-1, assigned address 3
    usb.c: USB device 3 (vend/prod 0x73d/0x50) is not claimed by any active driver.
    Initializing USB Mass Storage driver...
    usb.c: registered new driver usb-storage
    usb_control/bulk_msg: timeout
    scsi1 : SCSI emulation for USB Mass Storage devices
    Vendor: Eutron Model: Picodisk Tech 2 Rev: 1.00
    Type: Direct-Access ANSI SCSI revision: 02
    Attached scsi removable disk sda at scsi1, channel 0, id 0, lun 0
    SCSI device sda: 256000 512-byte hdwr sectors (131 MB)
    sda: Write Protect is off
    sda: sda1 } HERE!
    WARNING: USB Mass Storage data integrity not assured
    USB Mass Storage device found at 3
    USB Mass Storage support registered.
    As you can see the new device has been attached at /dev/sda1 as scsi disk.


    ======================
    C) Using your pendrive
    ======================

    To use your USB pendrive you have only to mount it; first make a new directory:
    # mkdir /mnt/pendrive
    Supposed that the device has been attached at /dev/sda1:
    # mount -t vfat /dev/sda1 /mnt/pendrive
    NB: in some documentation I found in the web, someone suggested to mount the
    device with 'auto' filesystem; in my experience, mounting the pendrive by this
    way caused the usage of DOS/fat16 filesystem with all its limits. So, if you
    do not want to format the pendrive to use a *nix filesystem, you should better
    use the 'vfat' option here.


    ===============================================
    D) Automatically mount the pendrive at the boot
    ===============================================

    Edit as root your /etc/fstab and add this line:
    /dev/sda1 /mnt/pendrive vfat noauto,user,rw 1 0
    Specifing 'noauto', you deny automatic mount of the device (as should be for
    external hard disk!); 'user' lets non-root users mount or umount the device;
    'rw' stands for the ability of reading AND writing.
    Now you can reboot and have fun with your new pendrive!

    Grazie Falco, la guida è davvero esauriente e sono riuscito ad accedere al pendrive. La salvo tra i documenti importanti.
    Ciao
