>Description:
When a "may-in-one" USB card reader (e.g. "9in1") is connected, only one out of (in my case) 4 slots is discovered and assigned a da device.
Only one LUN (0) is scanned; the card readers address their other slots with different LUNs.
The problem ist the same whether the USB device is persent at boot time or connected later.
>How-To-Repeat:
The same happens with two different card readers I have:
umass0: ICSI 2.0 Card Reader, rev 2.00/1.3a, addr 2
umass1: Generic USBMass Storage Device, rev 1.10/1.71, addr 2
>Fix:
1) use "camcontrol .. rescan" with the proper LUN. You have to exactly know the LUN.
2) Apply following patch to the kernel:

USBDEVUNIT(sc->sc_dev), CAM_LUN_WILDCARD));
if (xpt_create_path(&path, xpt_periph, cam_sim_path(umass_sim),
- CAM_TARGET_WILDCARD, CAM_LUN_WILDCARD)
+ USBDEVUNIT(sc->sc_dev), CAM_LUN_WILDCARD)
!= CAM_REQ_CMP)
return;
Result: now all 4 slots are automatically discovered:
