pywinusb with pyinstaller about pywinusb HOT 8 CLOSED

Hello @tanyanghan , could you run your binary in an Administrator shell?

I think the OS might be protecting the USB access to an un-trusted executable.

If this works on a admin console, either you'd need to change the binary properties manually, or you might need to add some sort of trusted certificate (check pyinstaller docs).

Hi @rene-aguirre, thanks for your response. I have tried running it as under an admin console, but it didn't make a difference. I also tried right clicking on the exe in Explorer and running the exe from Explorer as admin but it still didn't work.

I've signed the exe with a self-signed certificate which I added to the Trusted Root Certification Authority on my PC, but the result is still the same with the vID and pID all returning as zeroes. The signing appears to have worked because the properties of the exe in Explorer now shows This digital signature is OK.

Further digging, winapi.CreateFile() appears to be returning a valid h_hid handle and calling ctypes.GetLastError() returns 0 - ERROR_SUCCESS.

BUT when it tries to read the attributes hid_dll.HidD_GetAttributes(h_hid, byref(hidd_attributes)), it fails and ctypes.GetLastError() returns 6 - ERROR_INVALID_HANDLE.

@tanyanghan Could be an issue with your registry? Example: http://digital.ni.com/public.nsf/allkb/1D52B53149DD637686256CAA00565E47

I tried it, and it didn't seem to have made a difference.

Here's the problem. I was using Python x86-64 and it didn't work after pyinstaller packaged it up.
Python 2.7.14 (v2.7.14:84471935ed, Sep 16 2017, 20:25:58) [MSC v.1500 64 bit (AMD64)] on win32

It works with Python x86 (32-bit) after pyinstaller packages it up!
Python 2.7.14 (v2.7.14:84471935ed, Sep 16 2017, 20:19:30) [MSC v.1500 32 bit (Intel)] on win32
