I am working on WDM Video and Audio streaming drivers
for Win2K, XP,and Win98 for a PCI Capture/Playback
board. The Audio is projected as a ChildPDO of the
Video device. Once we install the Video driver, the
Audio device is detected and we install the driver for
it. The problem I am facing is that, when the audio
driver is loaded the install wizard asks for a system
reboot and shows the typical black exclaimation mark
(on yellow background)for the Audio device in the
Device Manager applet(the video device does not have
this mark and says that the device is working properly
in the properties->general tab). For the Audio device
the properties->general tab says:
"This device is not configured correctly. (Code 1)
You need to restart your computer before the changes
you made to this device will take affect.
To reinstall the drivers for this device, click
Reinstall Driver. "
This happens ONLY on Win2K and does not happen on XP
and Win98. On XP and 98 the devices are ready as soon
as I install the drivers and I don't need a reboot. I
have a common binary and INF file for Win2K, XP, 98
(different for video and audio).
Is there any thing I am missing in the INF files in
reference to Win2K. I am not able to find the reason
behind this behavior. Any help on this will be really
appreciated.
Warm Regards,
