Do know about -EPROTO yet, but resets happen with the ALi chip, that don't with the other cards. Sometimes, all seem to work (from the GUI user point of view), but the file is corrupted. $ cmp -l /media/disk/700MB-file.iso /home/me/700MB-file.iso | wc -l 1229584 The only sign that something's gone wrong is in syslog.

Let's play with usbmon, again, i hope it won't crash my computer every now then this time :-) Best regards, Guillaume B. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
