Anyone know if it is possible to configure a USB device
on WIN XP to be appear installed even when the device is
removed? My issue is user unplugs headphones, uses an
application that would normaly use the USB headphone, the
USB device is now missing, application reconfigures to
use on board audio. User plugs headphone back in,
accesses application. Application does not know to
switch back to USB device. If I could keep the USB
device appearing active, even when not plugged in, I
could avoid this condition. I have stumped Microsoft
Support line. Any ideas?

That is not the behavior of USB. The only way XP will detect a USB
device as active is if the device is connected. USB devices support
hotswapping and being able to unplug and connect them without rebooting
the PC by having the connect/disconnect automatically detected.

Windows Xp is built on Windows 2000/NT technology. NT releases the
configuration of the device when it does not find it at boot-up.

You can add a USB hub so that you can have more available USB ports. With
more USB ports, the user would not have to discconnect the headphones in
order to use other USB devices.
