On a more positive front, I've tracked down and have a fix for the issues we've seen on the GUI. Turns out that MacOS X 10.5 / Darwin 9 changes the behavior of threads, so that the fast-usb code's threads would not do flow control (notification of start / finish of individual threads) reliably. I've created a testing branch with changes that work well for me on 10.5, and should be backwards compatible with 10.4 (I'll try that tomorrow; requires a reboot). These changes allow the GUI to work for me, which completes the (short) list of issues that I know of between 10.5 and GNU Radio.
I would appreciate it if MacOS X users (10.4 or 10.5) could try out, and provide feedback on, the branch at:
http://gnuradio.org/svn/gnuradio/branches/developers/michaelld/usrp_fusb_fixand verify that USB transport works for them. You can do this via any USRP scripts, and/or heading into "usrp/host/apps" and executing "./ test_usrp_standard_rx" and "./test_usrp_standard_tx". - MLD
