Maybe you can find more help on the freebsd-usb list. BTW some mp3 players eg mine http://berklix.com/~jhs/txt/clipman/ seem to detect the power on the cable, & then turn on or off, & then devd see what the player has done, & itself removes devices or recreates (& if so with permissions that dont suit). Solutions include to move power switch of mp3 player to force on or off whatever, & on BSD end, either work as root, or hack the devd.conf so modes or ownership of device allow access to normal users. Beware if mp3 player decides to power down, that can cause DOS FS to disappear, mounts to fail, that if they were in use, might cause a crash, I reckon I've experienced that. Best experiment first on a spare BSD box, not a main server others rely on. Cheers, Julian -- Julian Stacey: BSDUnixLinux C Prog Admin SysEng Consult Munich www.berklix.com Mail plain ASCII text.
