[Libusb-devel] libusb0.sys filter driver.

[Jon S. <jon...@gm...>]

I know there has been work towards supporting libusb0.sys as a windows
back-end, and I was able to do some successful tests using it but I
was wondering if any progress as been made towards supporting the
filter driver as well. From my tests devices on the filter did not
show up when iterating through usb devices while ones using the
libusb0.sys driver directly did. Once I have more conclusive tests of
the regular libusb0.sys driver I will post my results here as well.

I have a few users who use the dev filter to have our app coexist with
the hardware manufacturers drivers and it has been invaluable for
testing what we do differently to debug what is going wrong. The issue
is if we move to libusb-1.0 on windows we lose both of those
possibilities, at least doing those with ease. If there is testing or
some simple coding I can do to assist I can devote some time I do not
already have devoted towards school and my other projects.

Thanks,
