Yes Zadig will install libusbk.dll when installing libusb0.sys
or libusbk.sys driver. However, it is not recommended to use
libusb0.sys (device driver mode or filter driver mode) with
libusb Windows (libusb-1.0 API).

Ref: https://github.com/libusb/libusb/issues/94

In general, you should use WinUSB driver to use libusb
Windows (libusb-1.0 API).

[pyusb-users] find_library considered harmful

[Hermann Hamann]

Hi dear maintainers.

 

I have compiled the results of the pick wrong library issue and some investigations in an issue on github.

However I could not attach the PDF file and therefore provide it here.

 

Please study it carefully.

 

I will not be here until september, so you have enough time to think and try to verify or falsify my thesis

before you respond.

 

The game is not over.

I will be back!

I will find these f.. installed libraries!

 

Hermann

Hi Jeff,

I have opened an issue on this topic. Please read it and try to falsify or verfy my thesis.

I will not be back to my mailbox before september, so you have ample time.


So long

Hermann
