    Subjectusb hotplug problems with 2.6.10
    Date
    From
    Alan,
    I had mentioned a couple weeks back that with kernel 2.6.10,
    the ability to hotplug usb keys in Fedora Core 2 and 3 has been broken.
    There is actually a bugzilla report on this with some useful information
    on manifestation of the problem....

    https://bugzilla.redhat.com/beta/show_bug.cgi?id=119140

    The problem can be hacked around for the moment in hotplug by
    repeatedly calling updfstab until the device appears in both
    /proc/scsi/scsi and /sys/bus/usb/drivers/usb-storage but it
    would be nice is this could be fixed in the kernel. Hasn't any
    distributions other than Fedora run into this yet?
    Jack
    The hack recommended by Jason Tibbitts that works around this problem
    is...

    ...its ugly of course but at least hotplugging usb keys work again
    under 2.6.10.
