I (think I) want to use AVStream in a WDM firewire audio driver for XP. My driver is loaded by AV/C when it detects the AVC Audio device on the 1394 bus; - What is the preferred method to send IOCTLs to avc / 61883 ? If IoCallDriver(), then what do I pass for the DEVICE_OBJECT param? - Will I still call InstallSubDevice() for the Wave and Topolgy devices? Thanks --------------------------------- Do you Yahoo!?
