[Discuss-gnuradio] FPGA compatibility number X310

I am setting up a new computer to talk to a x310 previously used on another 
system. I installed on this computer gnuradio and uhd on ubuntu 14.04 from the 
latest (yesterday) build-gnuradio script from Marcus Leech. All works fine with 
a N210.

However, with a usrp x310 on standard ethernet communication, uhd_usrp_probe 
--args addr= returns an error:

linux; GNU C++ version 4.8.4; Boost_105400; UHD_003.010.git-101-g4a1cb1f2
Error: RuntimeError: Expected FPGA compatibility number 18, but got 17:
The FPGA image on your device is not compatible with this host code build.
Download the appropriate FPGA images for this version of UHD.

I therefore runned (successfuly), as instructed, uhd_images_dowloader.py and 
then /usr/local/bin/uhd_image_loader --args="type=x300,addr=" which 
didn't show any error. I power cycled the x310 as I must after a fpga burn, but 
then the error of uhd_usrp_probe is still there.

Note than on the PC that was used previously with the x310 everything still 
works fine. On this one however, UHD_003.010.git-89-gb17b440d is reported for 
the uhd version... Is there a delay to be expected before the standard image 
fetched by uhd_images_dowloader is in agreement with the uhd version gitted by 
the build-gnuradio script ?

Thanks for your help.
