Oh, right, I was planning to address that one. This error message should have been silenced after we added support for the filter driver, as this is not really an issue if we manage to find the filter. I have now pushed a commit to fix this. > libusbx: info [get_interface_details_filter] assigned libusb0 symbolic link > \\.\ > libusb0-0001 Mmm, maybe we should set that info message to debug? What do you think?

Yeah, I think that's the same issue I mentioned when querying string descriptor 0xEE for WCID. Only seems to occur with libusb0.sys (either filter or regular) > 4) libusbk.sys --> does not work well. Yup... I'll try to see if we can get some more info with the debug driver.
