So, turning off the atapi attribute in files.usb for umass allows this
to work flawlessly:
umass0 at uhub1 port 4 configuration 1 interface 0
umass0: Sony Sony DSC, rev 1.10/4.10, addr 4
umass0: using RBC over CBI
scsibus0 at umass0: 2 targets, 1 luns per target
scsibus0: waiting 2 seconds for devices to settle...
sd0 at scsibus0 target 1 lun 0: <Sony, Sony DSC, 4.10> SCSI0 0/direct removable
sd0: mode sense (4) returned nonsense; using fictitious geometry
sd0: 63424 KB, 61 cyl, 64 head, 32 sec, 512 bytes/sect x 126848 sectors
umass0: at uhub1 port 4 (addr 4) disconnected
Now that I think of it, I may not have tried the a -current kernel
(since the scsi and atapi attributes were added) with the camera plugged
directly into the laptop - I used to have only something like:
umass* at uhub?
scsibus* at umass?
sd* at scsibus?
There's already some Sony quirks in umass_quirks.c; I'm not sure how/if
to tell this device to not use atapi and use scsi only. Here is the device
info from "usbdevs":
port 4 addr 4: full speed, self powered, config 1, Sony DSC(0x0010), Sony(0x054c), rev 4.10
