Fix: Patching sys/dev/usb/usbdevs for adding name for this device and patching sys/dev/usb/umass.c for adding quirk NO_SYNCHRONIZE_CACHE fixe the problem Patch attached with submission follows: How-To-Repeat: Insert a MPMAN player.

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) --=20 HPC
The usb/usbdevs part of the patch has been committed, but the quirk has only been committed to p4 so far.
