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.
