usb filter driver - constant serial number

Hi, i am new to whole driver develompent so i would like some pointers. I'm
trying to make my UBS printers (same vendorid and productid, different serial
number) to be detected as one ie. my idea is to set serial number to constant
value. Something like IgnoreHWSerNumXXXXXXXX registry key but that method is
not good enough for me because when i plug printer into another usb port,
windows detects it as new device. So, I would like to know it this possible
and how. Thanks in advance.

 

Why do you want to do this? So you don't get the hardware wizard?
Just get your drivers signed.

 

I'm working on POS terminal running XP Embedded (custom shell, no windows
installer and other limitations). System currently supports several different
printer models and I'm trying to build master image, that when cloned to all
other terminals, would enable easiest way to replace broken printer. My idea
was to install one instance of printer per model and make one of then
default. When that printer stops functioning, service guy brings new printer
and just replace it, if new printer is different model then set that model as
default. My wish is to make that system as much as possible fool proof.

 

default. When that printer stops functioning, service guy brings new printer

Looks like the additional efforts of the service guys with driver installation
costs much lesser then developing the USB bus filter

 

A good ( = clean, simple, quick ) solution IMHO is
a. Using IgnoreHWSerNumXXXXXXXX
b. Instructing the service people to connect the replacement printer exactly to same port.
Making this point fool-proof ( leave only one port accessible, etc).
