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
