Completely prevent serial mouse detection David Kerber <ns_dkerber[ at ]ns_wraenviro.com> 12/26/2008 3:13:29 PM We've got an XPe device that uses a PS-2 mouse during intial setup, and connects to serial devices during operation. However, the PnP system sometimes (not always) appears to be detecting this device as a mouse, and popping up a notice about trying to install a serial mouse driver, which fails because it's logged on as a limited user, who doesn't have authority to install new hardware. How can I completely prevent XPe from trying to detect serial mice during startup and operation? I have already put /fastdetect in the boot.ini, which is supposed to prevent that during ntdetect, but I can't figure out how to stop PnP from detecting it during OS startup. /noserialmice doesn't seem help it (and I didn't expect it to, since that's supposed to only do anything for NT) -- /~\ The ASCII \ / Ribbon Campaign X Against HTML / \ Email!

You can prevent the auto detection and installation of any Pnp-devices by removing or renaming the newdev.dll - maybe this already would help? -ras -- Ralph A.
