I have a multifunction printer (EPSON DX7000 series for what matters) with an SD/CF reader in it. FreeBSD 7 correctly recognises the media (creating the entries /dev/da0 and /dev/da0s1) if the media is inserted before the printer is powered on (or the USB cable is plugged in), but it doesn't see the media if i insert it _after_ connecting the USB cable (or turning on the printer, again). What happens without media is that /dev/da0 is created when the USB is connected, but then reading from the device fails and no events are reported even after inserting the media. If I do a 'camcontrol rescan 0' then I see the following into syslog: Oct 24 15:11:00 bsd7 kernel: cam_periph_alloc: attempt to re-allocate valid device pass0 rejected Oct 24 15:11:00 bsd7 kernel: passasync: Unable to attach new device due to status 0x6: CCB request was invalid Oct 24 15:11:00 bsd7 kernel: cam_periph_alloc: attempt to re-allocate valid device da0 rejected Oct 24 15:11:00 bsd7 kernel: daasync: Unable to attach to new device due to status 0x6 and /dev/da0s1 is not created. /dev/da0 does produce valid output (so e.g. fdisk da0 gives me the various partitions) but of course i cannot mount it. Is there any command that i can use to either rescan the entries in the disk, or (perhaps too crude, though) rescan the usb bus ? cheers luigi
