Windows XP message says "device driver for com1 is preventing the machine from entering standby mode"

Recently I am seeing the subject message whenever I leave the machine for 15+ minutes. It tries to go into standby mode but com1 stops it.  This has started after I started using a memorex U3 traveldrive (1gb flash drive). I have checked the driver for com1 and MS says it is current.

I would try uninstalling the driver and reinstalling it.  May have just been a corrupted install for whatever reason.  The driver by no means should be blocking your standby.

I disabled the com drive -- that might do it. I am leaving for a few hours - we will see if that does it.

THANKS to  BOTH of you for such quick responses.

Yeah good point out slam69... i totally overlooked the fact that it was a com1 he was talking about.  I guess i saw travel drive and immediatly thought USB issues.... I blame this monday stuff.

Thanks for the simple solution - I should have thought of it myself. The installation of this flash drive was confusing and it did show the drive as utilizing the com port as well as the usb port -- like there were two devices in one. When I disabled the com port, it went back to what I would have expected. ??

Disabling the com port fixed everything!  Not sure why the installation of this flash drive got tied to the com port and the usb port.  Even though it showed a connection with the com port -- it worked fine, just gave off unusual messages.
