Will a SD card reader solve this problem?

[Ada Cheng]

Good morning,
         I am trying to connect my Minolta Z2 camera with my box, currently 
running 4.10 stable.

The following devices are included in my kernel:
device scbus
device da
device pass
device uhci
device ehci
device ohci
device usb
device umass

After rebuilding the kernel and rebooting, I tested the configuration by 
plugging in my camera. The following is the output of dmesg:
umass0: KONICA_MINOLTA DiMAGE Z2, rev 2.00/1.00, addr 2
umass0: BBB reset failed, TIMEOUT (this is repeated if I don't unplug the camera)

If I do a camcontrol devlist I obtain
<KMCA DiMAGE Z2 1.00>              at scbus1 target 0 lun 0 (probe0)

so I guess the camera is recognized but no device node was probed.

I am also getting the following error when i do
$mount -t msdos -r /dev/da0s1c /camera
msdos: /dev/da0s1c: Device not configured
which I guess isn't too surprising.

I have read various threads regarding this TIMEOUT failure error and 
some has suggested doing some quirks with the src/sys/cam/scsi/scsi_da.c 
file which I am not comfortable with doing.  Will a SD card reader solve this 
problem? Any help is much appreciated.

Many thanks in advance.
Ada
