I think that may be a bug. I see that if you have an XPT_CONT_TARGET_IO
CCB, for an INQUIRY, as you would in your case, it would be CAM_DIR_IN, but
would need to copy the data from userland into the kernel.
It looks like it changed in SVN revision 345656.
I have CCed Alexander Motin, he originally wrote that change and can take a
look at it.
