It seems the biggest block (complex) is 4095 samples. Can you go larger than this with some software hacks? Also, when you get a "U0" How do you know how much data you dropped?
Take at the defines in fusb_sysconfig_linux.cc (given you're using linux). This is where these numbers come from. However, you don't have to change the defines, you just need to change how the usrp_basic_rx() is called, and change the parameters there. The defines are just the default.
The comment "// fewer kernel memory problems" with 4*1024 may suggest that Eric chose some of these parameters for a reason. Unfortunately he's on vacation for the next 3 weeks I think.
