Unfortunately, it doesn't appear to be a problem within LiS, just
reported by LiS.

LiS' open_mods() calls lis_qopen() which in turn calls the open
routines of the modules associated with the devices being opened.
It is one of the module's open routines (part of CS?) that is
reporting error 16 (EBUSY).

Note that this path is only followed when an existing stream is
being reopened.  Given the error EBUSY, reopening may not be
supported by that module.   It may be that you need to change some
configuration to use /dev/XX1 and /dev/XX2 rather than both using
/dev/XX1.  Or it may be that the /dev entry is built incorrectly
and should be a cloning device (have the major number of the
clone driver and the min number equal to the add-on module's
major).

In any event, it looks like the problem is CS-specific.
