I tried. Works for about 5s at my site. Im a really unlucky guy ^^,
I checked the /mnt/1wire/12.xxxxx/PIO.A by hand afterwards (with cat) and got
an "invalid argument", too. The uncached directory was empty after I got the
failure. Done "killall owfs", restarted, worked again for ~5s.
dmesg showed no USB problems at any time.
