USB print driver works only at one single USB Port- Driver is re-installed when moved to different USB port

If I don't plug my printer back into the same port as first installed, the "found new hardware" screen appears, and wants to re-install the driver at the new port. This happens both with my laptop, and Destop systems.  OS: XP Pro   Printers: HP Laser 1000, and HP Multi-function printer.

Are USB print drivers "port independant", or associated only with individual ports??

This is normal behavior if the device you are connecting to the USB port does not have a specific identifier associated with it.

Windows XP relies on serial number identification to distinguish between attached printers. However, the current USB specification does not require devices to provide a serial number and is, therefore, not provided by some printer manufacturers. When connecting such a printer (no serial number in ROM), Windows XP cannot identify it and enumerates it as a new printer..

Your printers most likely do not have the serial number identification in them.

here is the microsoft page relating to USB ports and windows

Here is USB completely explained for version 1.1 ad 2.0 also has other resources.

Yes it is a "feature" of Windows, and it applies to cameras, card readers, pdas, etc.

Strangely enough, it does not apply to some other OSes.
