Hello...
I'm not expert in python nor pyinstaller. But I try all (at least I think) possible solutions to solve problem.
So as problem is near same as in other example I steal minimal program and it is this piece:
all work is done in WinXP running virtualbox hosted by ubuntu.

import usb

print 'pyusb.version:{}'.format(usb.__version__)

dev = usb.core.find()

print dev

and result is:

_pyusb.version:1.0.0rc1
Traceback (most recent call last):
  File "<string>", line 3, in <module>
  File "site-packages\usb\core.py", line 1263, in find 
usb.core.NoBackendError: No backend available
t returned -1_

I do compile with: pyinstaller -F c:\xx\t.py and here is log:

The error message clearly says usb.core.NoBackendError: No backend available. So the backend is missing. And thus the instructions of my link above are the way to go. You need to find out, which backend is required and why it is i missing.

Something is wrong here.
if I run program with "python myprog.py" it works as should.
If in same system execute:
pyinstaller myprog.py
myprog.exe
then I got missing backend error.
And I don't have a clue how to solve that.

When you bundle with -F option, you get a one-file app. One hopes that everything the app needs to run is in that one file. Python interpreter, all imported modules, everything. So it does not matter where you run it, if something called a "backend" was not bundled into the one file, it will be "missing".

The question is, what is this "backend" thing that is not being picked up? The question is a little easier to answer if you bundle with the -D option instead. Then you can inspect inside dist\myprog\myprog to see all the things PyInstaller collected.

What is this module usb, it does not seem to be a standard module and I do not see it at pypi.python.org. So I cannot tell what it means by "NoBackendError".

Hello...
I do try with -D option too with same result.
module "usb" is used to communicate with usb devices. https://walac.github.io/pyusb/ or https://sourceforge.net/projects/pyusb/
It's available in pip too.
As I understand the pyusb (module usb) is just a wrapper to libusb0.dll or libusb-1.0.dll. And these dll's needs to be installed separated. And with my understanding that's is backend.
The trouble is that when I start python myprog.py all things works great. But if I build with pyinstaller the backend is reported missing but it is in system! the dll is in dist folder (-D option) too.
Something strange is there.
these files are collected in dist folder.
(should be something like _usb.pyd here too?)

 _ctypes.pyd
_hashlib.pyd
_socket.pyd
_ssl.pyd
bz2.pyd
libusb-1.0.dll
Microsoft.VC90.CRT.manifest
msvcm90.dll
msvcp90.dll
msvcr90.dll
python27.dll
select.pyd
t.exe
t.exe.manifest
unicodedata.pyd

Sorry, I did not understand the lib was called pyusb. Now I see it at pypi.
I will not be able to solve this but here is some info for anyone else.
One, if you want to see pyusb loading the backend, the code is here
Two, PyInstaller already has a hook for usb and it is much more complex than the usual hook.
(C), there is also a run-time hook which is also fairly complex.
IV, looking at the output in your original post I see

missing module named usb.core.USBError - imported by usb.core, usb.backend.libusb1, usb.backend.libusb0, usb.backend.openusb

and also,

missing module named 'usb.backend.libusb01' - imported by C:\Python27\lib\site-packages\pyinstaller-3.1.1-py2.7.egg\PyInstaller\loader\rthooks\pyi_rth_usb.py
missing module named 'usb.backend.libusb10' - imported by C:\Python27\lib\site-packages\pyinstaller-3.1.1-py2.7.egg\PyInstaller\loader\rthooks\pyi_rth_usb.py

So, yes, there is perhaps some problem with the hook.

the pyusb support libusb01, libusb10, libusbx, libusb-win, openUsb.... and only one need to be present. so I assume that missing libusb10 and libusb1 is not important in my case but missing libusb01 it is as I rely on this one. And I assume that hook is the trouble...

I try do do some debug. in hook-usb.py I just print result and library is found. So that part seems to work.
but pyi_rth_usb.py I can't understand how they work.
For start I modify beginning to se if backend is loaded. I just put some prints there.

try:
    print "!!!! Trying libusb10"    
    import usb.backend.libusb10 as libusb10
except:
    print "!!!! Failed"

try:
    print "!!!! Trying libusb1"    
    import usb.backend.libusb1 as libusb10
except:
    print "!!!! Failed"
try:
    print "!!!! Trying libusb01"    
    import usb.backend.libusb01 as libusb01
except:
    print "!!!! Failed"
try:
    print "!!!! Trying libusb0"    
    import usb.backend.libusb0 as libusb01 
except:
    print "!!!! Failed"
try:
    print "!!!! Trying openusb"    
    import usb.backend.openusb as openusb
except:
    print "!!!! Failed"

and result is

!!!! Trying libusb10
!!!! Failed
!!!! Trying libusb1
!!!! Trying libusb01
!!!! Failed
!!!! Trying libusb0
!!!! Trying openusb

so librrary libusb1, libusb0 and openusb are found!
So I go next steep. to print candidate list

def get_load_func(type, candidates):
    print "!!!!!!!!CandidateList ",candidates

and got

!!!!!!!!CandidateList  ('usb-1.0', 'libusb-1.0', 'usb')
!!!!!!!!CandidateList  ('usb-0.1', 'usb', 'libusb0', 'libusb')
!!!!!!!!CandidateList  ('openusb',)

so this seems to work too.
but next thing was:

def _load_library():
    exec_path = sys._MEIPASS
    l = None
    for candidate in candidates:
        print "!!!!!! candidate=",candidate

And there I don't get any output. so that loop (for) is not executed at all!
So there is def inside def and I don't understand the parameter passing.
the def get_load_func(type, candidates): got candidates as I can print them.
but def _load_library(): inside def get_load_func(type, candidates) has no parameters.
I expect to be candidates passed to _load_library() too but it doesn't as print there return ''

Any idea?

Did you determine which library is being loaded/used when the application is not frozen?

eslavko commented Apr 9, 2016

Hello...
I don't know why but sometime the libusb0 and other time libusb1. I solved that with installing python on target system so pyinstaller is not needed. But this is still the bug in pyinstaller.

...maybe library loaded is device dependant as I do communicate with more physical devices.

I'm having the same problem right now (using PyInstaller 3.2 on Windows 10), so I try to give some more input:

The NoBackendError from the original report is in fact caused by pyusb not being able to find a libusb*.dll - manually copying the DLL to the dist/project folder fixes that, and the application will work as expected. But of course we cannot build a single .EXE that way, which is what I'd like to do.

Looking at hook-usb.py, it seems that the hook intends to add the DLL to binaries, but fails to actually do so, because the DLL in question is installed to C:\Windows\System32, and WinExcludeList excludes everything below C:\Windows. The exclusion happens after the correct path is already found, in _resolveCtypesImports() (hook-usb.py Line 45), which uses WinExcludeList through include_library() from dylib.py.

Unfortunately I'm not familiar enough with PyInstaller's concepts to actually solve that problem. I tried to modify hook-usb.py so that the DLL is not excluded, but then it gets copied to into a subfolder "libusb0.dll", which does not work either (it must be in the output dir directly, otherwise pyusb won't find it). The same happens if I try to add it manually in the .spec file through binaries.

How can we add some files directly to the output folder root, without subdirectory, like PyInstaller 2.1 does it?

Update: The following seems to work (in the .spec file):

binaries = [
   ('C:\\Windows\\System32\\libusb0.dll', '.'),
]

a = Analysis(['myscript.py'],
    ...
    binaries=binaries,
    datas=[],
    hiddenimports=['usb'],
    ...

I think I found the problem in the hook, as you noted it was the directory. I fixed that and added another detection method which uses the pyusb finder directly. I have a branch with the changed hook 23901eb. If you could try the hook, that would be great.

The test framework is currently not running the test for usb, and I am trying to get that going next.

How are you modifying the .spec file? I am using the command line interface for this so it looks like this:
pyinstaller --console --onefile main.py
It then generates the .spec, how can I modify it and then use it to fix this problem?

EDIT:
I figured it out, I didn't realize that you can use pyinstaller with the .spec file, so my command line command looked like this:
pyinstaller main.spec

Everything works now. Will leave this here if anyone is confused like I was.
