Hi,
I have an application that automatically brings my computer out of standby
and immediately issues a command to my USB-based (1.1) infrared blaster.

The problem is that it seems Windows XP likes to "reset" the USB ports as it
comes out of standby, which takes about 5-10 seconds. I know this, because I
can hear the generic USB plug-in sound. And while the reset is happening,
the command to the infrared device takes place and fails (because Windows
doesn't think the device is present until the "reset" is complete).

By the way, the USB device stays on all through the S3 standby (enabled with
the correct motherboard jumper settings). So, this "reset" seems somewhat
useless to me.

Does anyone know how to stop Windows from re-registering the USB port after
S3 standby?

I'm sorry that this is more of a configuration question than a development
one, but I'm not having any success elsewhere.

Thanks,
Aaron
