compact RIO 9068 and GPIB

I have a Compact Rio 9068 running the NI Linux Real-Time OS.  I wanted to attach a GPIB-USB-HS+ to add a GPIB interace to it.  My Problem is that I cant seem to install NI-488.2 on the 9068.  I have it installed on my computer, and in MAX I have the option to install 488.2 on a PXI controller I have, but It will not give me the option to install it on the Compact RIO chassis.  Is there no NI-488.2 for  the NI Linux Real-Time OS?  I cant seem to find anything about it in any documentation.

Thanks

Mike
