    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]
