Com port not working after upgrade

[Allen]

I recently upgraded from ME to XP on an HP laptop. When
I boot the computer, the com port doesn't work. I can go
to device manager, remove it, then use Add New Hardware
to reinstall it, and it works fine until the next time I
re-boot...then I have to repeat the process. Any
suggestions would be appreciated!

What do you have connected to the comm port?

WinXP has been known to detect some serial devices as plug-and-play serial
pointing devices.

Check in device manager for the presence of serial pointing devices, and
check which comm port they are using. If you find one, click properties and
choose disable. If you delete it Windows will re-install it.
