Well, finally I did more testing and with my patch (added quirk
NO_SYNCHRONIZE_CACHE in umass.c) the system allow to mount, read,
write. But it seem that write sometimes failed :
Symptom:
mount the key
cp mp3 file
md5 file
umount the key
re-mout the key
md5 file give an other sum (and the sound is horrible)
I'm not specialist of the usb/umass quirk. Is there anything else to
try ? (FYI the mp3 mount/read/write like a charm on linux xubuntu)
Thanks for any help ! This patch is for helping my daughters to use
their mp3, help me to answer to their question "Dad, why don't you
install linux everywhere ?" :-) (No flame, just kidding)
