curious about da_quirk_table - FreeBSD

Greetings, I have an usb flash disk which does not support cache synchronization. Usb vendor 0x1005. (The inscription on it says "Apacer HandySTENO"). On FreeBSD 5.3 RELEASE it generates several of umass0: Phase Error, residue = 0 (da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0 error messages. I've looked in Google and in the source and found da_quirk_table array in scsi_da.c. I've added my disk data there and the disk started working... I'm just curious is that the right way to do this and if so do you gather the data....

    Greetings,

    I have an usb flash disk which does not support cache synchronization.
    Usb vendor 0x1005. (The inscription on it says "Apacer HandySTENO").

    On FreeBSD 5.3 RELEASE it generates several of

    umass0: Phase Error, residue = 0
    (da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi
    status ==
    0x0

    error messages.

    I've looked in Google and in the source and found da_quirk_table array
    in scsi_da.c.
    I've added my disk data there and the disk started working...
    I'm just curious is that the right way to do this and if so do you
    gather the data.

    Default Question: USB block dev, Olympus Camedia digital camera

    Hello everyone,

    I am new to BSD-style operating systems, and currently reading about and
    seriously considering a migration from Linux to free BSD on my home machine.

    Before I do that, I would like to make sure (as far as possible) that my
    critical applications will continue to work, one way or the other.

    It seems that the Olympus Camedia (C-1) digital camera does have some
    quirks that require a cludge for the kernel, so it can be mounted as a
    block dev for my Linux kernel version, although I hear that newer
    kernels do support that quirk out of the box.

    I was wondering, whether anyone here is using such a camera under
    freeBSD, and can tell me whether it can be mounted under 5.3 without
    such a hack.

    Thanks in advance,
    Peer

    Hello Peer

    I have an Olympus Camedia 3000 Zoom and it will not work directly
    connected via usb with FreeBSD. Your best bet is to get a usb card
    reader and then plug your card into it. I find it quicker and easier
    doing it that way.

    Good Luck
