freebsd stable - Apr 2004 - USB/CAM multi-lun devices

Dear colleagues,

trying to connect Apacer multi-flash USB reader

[usbdevs -v]
port 2 addr 2: full speed, power 500 mA, config 1, Embedded Reader(0x0240),
Apacer(0x0d7d), rev 1.00

I got only the first sub-reader connected:

Creating DISK da0
pass0 at umass-sim0 bus 0 target 0 lun 0
pass0: <Apacer Embedded Reader 3.02> Removable Direct Access SCSI-0 device
pass0: Serial Number \^_
pass0: 650KB/s transfers
(da0:umass-sim0:0:0:0): READ CAPACITY. CDB: 25 0 0 0 0 0 0 0 0 0
(da0:umass-sim0:0:0:0): NOT READY asc:3a,0
(da0:umass-sim0:0:0:0): Medium not present
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <Apacer Embedded Reader 3.02> Removable Direct Access SCSI-0 device
da0: Serial Number \^_
da0: 650KB/s transfers
da0: Attempt to query device size failed: NOT READY, Medium not present

I tried to detect this device under -current snapshot from 20040422, and it
successfully detects reader as multi-lun device, creating da0 to da3 disk
devices (some of them miss to create s1 partition, but this is another story)

I looked into sources a bit, and google also, but without much success. So, am
I right in my assumption that -stable does not support multi-lun devices at
all?  And, how much effort would it require to port it from -current?

Of course, I would be glad to test solutions/patches proposed.

Sincerely,
D.Marck                                     [DM5020, MCK-RIPE, DM3-RIPN]

Well, I suggested this to someone else this morning.  It didn't work
for him, but maybe it will for you (it does for me).  Use camcontrol
to rescan the other LUNs, e.g. camcontrol rescan 0:0:1.

You can also add an entry to /etc/usbd.conf to run a shell script that
does rescans if you attach the device after booting.  If necessary
you can extract the bus and target number from the output of
"camcontrol devlist".

As far as I know, there's no way to detect insertion of a card.
