    My USB drive is kingston 120 MB. It is formatted
    as FAT. It is perfectly working on MS Windows. But
    it is giving trouble in Linux RH 9. Sometimes,
    it works, sometimes it does not. Lately, it has
    completely stopped working. Though, when I use
    the same slot and use it in Windows, it works.

    Here are some diagonostic steps that I took.

    Step:1 dmesg | grep usb
    usb.c: registered new driver usbdevfs
    usb.c: registered new driver hub
    usb.c: registered new driver usb-storage
    usb.c: new USB bus registered, assigned bus number 1
    usb.c: new USB bus registered, assigned bus number 2

    Step 2: lsmod | grep usb
    usb-storage 69332 0 (unused)
    usbcore 78784 0 [uhci usb-storage]
    scsi_mod 107160 3 [usb-storage sg sr_mod
    ide-scsi]

    Step 3: Then I insert the USB drive. Suddenly the
    screen displays:
      hub.c: already running port 2 disabled by
             hub (EMI?) , re-enabling..
      hub.c: cannot enable port 2 of hub 1, disabling
             port.
      hub.c: maybe usb cable is bad.

      And I am not returned to the prompt. I hit the
    <enter> key to come to the prompt.

    Step 4: I try to install the usb drive by the command
            # mount -t vfat /dev/sda1 /usbdrv
            mount: /dev/sda1 is not a valid block device.
    So, it does not get installed.

    Another curious thing happens. On my computer(Laptop)
    I have one hard drive and two partitions. One is C and
    the other one is E. (There is no D). I have my CDROM
    on F. Now, I happen to have two USB drives, both
    Kingston. The one which is working in Linux, when
    installed in windows, installs itslef as G. While the
    one that does not work in Linux, when installed in
    Windows, installs itslef as D. Why do they take on
    different drive names. I do not know. I do not install
    them simultaneously. I install them one by one.

    Any suggestions, how to make it work in the Windows.
