Instructions for Windows users #26

I think the Windows installation guide should also list a method that does not block CAM from accessing the device.

It would be nice if there was a user-friendly way of install the libusb 1.0 client libraries on Windows. On liquidctl I had to settle for a manual guide to how they should be installed, but that is not optimal.

Anyone willing to write a script that does the necessary steps (download the appropriate release from libusb and copy the dlls to the correct places, taking into account the different ways Python might be installed)?

I am a little confused about all these alternative libraries and versions. E.g. is the libusb project from github much different from the libusb-win32 version? They also suggest Zadig for an easy installation process like we do here: https://github.com/libusb/libusb/wiki/Windows Maybe it works only simultaneously with CAM as a filter driver installation instead of the replacement. Did not get this to work easily and I was happy to never see CAM again though :-)

Libusb is just a cross-platform library to access USB devices. On Windows, it is compatible with the generic HID device and some others; on Linux it always runs with its own driver, but there we also have detach/reattach APIs to return control after we're done with the device. Oh, and libusb-win32 packages an older version of libusb (0.1).

The main issue I see with using the Zadig tool: it will only install the libraries in a user-friendly way if you force a driver change... but that also brings incompatibilities, most notably with CAM but also with other tools that might come up.

Ideally there would be an automated/easy way to install libsub without touching the driver. Because, as far I can see, the generic HID driver supplied in Windows is the optimal one for us and our users: we don't use any features from the non-standard drivers.

P.S. liquidctl in particular is not affected with the choice of driver and libraries because it is using the same USB stack; as long as it works with krakenx, it works with liquidctl... and vice-versa.

Thanks for the info. I will have a look into this on the next weekend.
