As suggested by you, I am now using the usrp_standard.h to implement USB 2.0 interface for Windows. However, I am facing a problem.

The function usrp_loads_standard_bits() in usrp_prims library loads the FX2 firmware by calling the following two functions:

In short are we trying to access the std.ihx firmware file by calling these two functions? In Windows ofcourse my firmware would not be lying in the directory specified by std_paths.h (/usr/local/share). Shall I change the directory path in std_path.h library, to some path where I have downloaded std.ihx myself? Also, I cannot use functions such asĀ access (path, R_OK) in Windows, because it is a function of unistd.h which is only available for Unix/Linux. How should I go about this problem, so that the firmware can be loaded into the FX2 through through Windows platform?

I am having a similar problem getting two USRPs to run on one computer
on NetBSD. gnuradio can only run one USRP at a time. It can only run
USRP #0 and when I create a usrp source/sink with which=1 it says
"Unable to find USRP #1".

Are you saying more needs to be done than specifying which=1?

Where are these constructors mentioned:
usrp_basic, usrp_basic_rx, usrp_basic_tx, usrp_standard,
usrp_stardard_rx, usrp_standard_tx.

I ran the gnuradio-examples multi_usrp_oscope.py as well. It also is
"Unable to find USRP #1", so I think there is an incompatibility with
gnuradio/NetBSD regarding multiple USRPs.
