The sysctl is a suitable solution for the shutdown issues. It is not suitable solution for the general use of using a memory stick to for example quickly transfer files. Once the memory stick is plugged into the usb port, it must remain there unless one wants to reboot the system. I rebuilt the kernel with USB_DEBUG and CAMDEBUG enabled. I need to wade through a rather large /var/log/messages to see if anything appears unusual. -- Steve _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
