If your interface is vendor defined then you should be able to load whatever driver you want on that and it should work just fine with the USB class drivers for HID and audio.

When you say interface you mean USB interface, right? We already have Audio Control, 2xAudio Streaming and a HID interface in our composite device. If we add an additional interface which would use EP0 for Vendor specific requests would we be able to load the WinUSB driver and have the inbox drivers for audio and HID at the same time? Thanks in advance.

We are considering to use it for FW upgrade purposes for our USB audio device (audio control+audio streaming+HID) but we are not sure if there is a way to load this driver together with the inbox usbaudio and HID drivers. We used a filter driver in the past but WinUSB seems much more convenient. The available information on WinUSB are very limited. Thanks in advance.

To use WinUSB as a driver, WinUSB must be "THE" driver for the interface. So, if you need usbaudio and/or HID on the interface, you can't use WinUSB at the same time. ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.com/
