just to take a step back… were you able to solve the make check

Hi
I installed fresh version of Cygwin. I followed the steps again I think
I installed wrong version of some packets, now I have it working but I
can not run test_counting.py .
–Alaelddin

it works now, thank you
But, when I tried to run usrp_spectrum_sense.py I got this

$ python usrp_spectrum_sense.py
Traceback (most recent call last):
File “usrp_spectrum_sense.py”, line 9, in ?
from usrpm import usrp_dbid
ImportError: No module named usrpm

what is wrong now please.

Traceback (most recent call last):

This is normal for Windows libusb0 0.1.10.1-3 the first time you try to
access the USRP. If you try it again (without removing power to the
USRP)
it should work. See http://www.gnuradio.org/trac/wiki/WindowsTips for
more
tips on using GNU Radio with Windows.

I found that I am using libusb-win32 version 0.1.12.0-1, I change it
to version 0.1.10.1-3. I plugged TX and RX in my USRP device. but I got
this error.

$ python test_counting.py

Can you see the usrpm in …/site-packages? if not, it was not built
correctly.
