USB printer goes AWOL



My Lexmark X125 disconnects randomly, usually after 2 to 3 days. There
is no power timeout set in
device manager for any of the USB host controllers or hubs (no USB
power required).
The tray Icon turns from a diamond shape to an "X" and the settings
utility will not open.
Dis-and re-connecting the USB and power connections does nothing to
bring it back. Only a reboot.
If I disconnect the power to the printer before it goes AWOL it will
work OK after just re-connecting the power .
Lexmark support tells me repeatedly to un- and re-install the
software, update to latest drivers, etc.
The are clueless.
(My system is WIN2K/SP4, MoBo is ASUS P4S800D-X)
