I have a "Hama" USB stick, 16G that creates no /dev/da* any more, though
it used to (tested on 2 PCs). Maybe it's dead ? The LED still flashes. Or just
gone weird ? Something I could fix with some CAM magic ?
Is it exhibit strangeness worthy of someone debugging ? (for
the sake of FreeSBD, not the stick) in which case I could post it to
whoever fancies improving FreeBSD ? (No valuable data on it).
