Zebediah Figura : wineusb.sys: Expose composite device interfaces.
Module: wine Branch: master Commit: 4e5eaba51f447100f19a92e3756c44bec1df2bff URL: https://source.winehq.org/git/wine.git/?a=commit;h=4e5eaba51f447100f19a92e37... Author: Zebediah Figura <z.figura12(a)gmail.com> Date: Wed May 11 19:01:50 2022 -0500 wineusb.sys: Expose composite device interfaces. On Windows this is the job of usbccgp.sys, a separate driver that layers on top of the base USB driver. While we could take this approach as well, implementing usbccgp is a lot more work, whereas interface support is effectively built into libusb. This patch helps us get closer to installing and running the Hauppauge cx231xx drivers.
