Hi! Today I patched a USRP2, Rev 4.0 with the UHD_003.002.000-e03f7c7 images in order to use it with MatLab AND GNU Radio's GRC. - This is the log taken from a Linux 10.4 LTS system, attached USRP2. Previously this setup worked very well. Now that I updated... it's broken. The IP setup had been tested with both static IP, and without.

So the firmware and the fpga are loaded. I used the latest available revision (http://www.ettus.com/downloads/uhd_releases/master_images/) from the master branch. Since the update I cannot probe successfully with either usrp_probe or with uhd_usrp_probe. Even if I change the kernel parameter according to the UHD suggestion I don't get a working setup. I'm using GNU Radio v3.4.0-101-g7e2b45b8 from the Git repo - built a week ago or so. Since there's just one Firmware image for my USRP2, and one FPGA image, and I tried n times... I guess there's something else that's wrong. I'd like to ask for a compatibility matrix: which UHD revisions work with GNU Radio? For now it's try and error.
