Unfortunately there is no easy way. Hardwiring as such is impossible with USB devices. You can camcontrol -v to get a clue about which da* is part of which umass* device. With devinfo -v you get the serial number of each umass device (if your devices have serial numbers) and the connection tree. You can use devd to get an attach/detach notifications to setup softlinks in /dev which point to the changing nodenames. Unfortunately devd is started befor /usr is mounted so the tools you can use in devd scripts are limited. In case of automounting I would suggest you identify the device at mount time instead of going the devd way. This is with 5.3 and current - under FreeBSD 4 things are a bit more complicated. happy scripting... -- B.Walter BWCT http://www.bwct.de bernd@bwct.de info@bwct.de
