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.
