    thumbdrive on /dev/sda1 gone?


    i think it might have to do with the kernel as i've been trying to make the kernel smaller and smaller. everything else works fine (including my usb keyboard and mouse) except for the thumbdrive. I didn't change anything relating to USB storage devices in the kenrel (kept that section the same), and i took out some things from the scsi section (is scsi support necessary for a thumbdrive?? it's mounted at /dev/sda1....).

    "dmesg | grep -i usb" gives the following output:

    it finds the thumbdrive without any problems, but the directory /dev/sda1 no longer exists (and this is where my /etc/fstab searches for it), and now the thumbdrive no longer works and can't mount.

    can someone help me with this?

    thanks in advance!



    EDIT: i found that you do need scsi support for usb storage devices (thumbdrive included). what usually needs to be compiled into the kernel to enable a thumbdrive?

    scsi, usb, usb thumbdrive and the filesystem you keep on the thumbdrive (usually vfat). At least they are the ones I include, there might be something else too which I dunno about...

    ok, i'll show you what i do have enabled (pertaining to usb, scsi, and file systems)

    File Systems > DOS/FAT/NT Filesystems
    * MSDOS fs support
    * VFAT (Windows-95) support
    (435) Default codepage for FAT
    (iso8859-1) Default iocharset for FAT
    <M> NTFS file system support

    Device Drivers > USB Support
    * Support for Host-side USB
    --Miscellaneous USB options
    * USB Device filesystems
    --USB Host Controller Drivers
    * EHCI HCD (USB 2.0) support
    * OHCI HCD support
    * UHCI HCD (most Intel and VIA) support
    * SL811HS HCD support
    <*> USB Mass Storage Support
    ...* Datafab Compact Flash Reader support (EXPERIMENTAL)
    ..,* Freecom USB/ATAPI Bridge support
    ...* ISD-200 USB/ATA Bridge support
    ...* Microtech/ZiO! CompactFlash/SmartMedia support
    ...* SanDisk SDDR-09 (and other SmartMedia) support (EXPERIMENTAL)
    ...* SanDisk SDDR-55 SmartMedia support (EXPERIMENTAL)
    ...* Lexar Jumpshot Compact Flash Reader (EXPERIMENTAL)

    Device Drivers > SCSI device support
    * SCSI disk support
    * SCSI generic support
    ... > SCSI low-level drivers
    ....... > BusLogic SCSI support


    Is there anything I'm missing? I'm thinking it's something within Device Drivers > SCSI device support > SCSI low-level drivers, but I'm not sure.

    Thanks in advance

    I think you have what you need, but I doubt you need all the different HCD's, I have only uchi for example since that's what my USB ports work with.

    Hmm, that was a bit weird... Here it's always /dev/sda. Is it something in the new kernel update, I'm still running a custom 2.6.14.0?

    I'm not sure....this is the second time the thumbdrive switched to somewhere else from what i recall. I can't remember what it was originally though (before it was /dev/sda). oh well...i'm just glad to get it working again
