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.
