I've been asked to update an old USB audio install for Vista. My USB device understands a set of vendor specific commands that access an I2C interface within the device. The existing install uses an upper filter driver that simply translates IOCTL commands using UsbBuildVendorRequest() with a DispatchControl function for IRP_MJ_DEVICE_CONTROL. Can I send vendor specific USB commands from user mode or will I need to port my filter driver to Vista? ****************** 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/
