vista driver update

Raj

I am working on windows device driver for 1394 for 32-bit Vista. I found it
strange that I cannot update my already-installed unsigned driver after I
made changes to driver code and recompiled. I was able to install driver
first time. But updating driver is the problem. It updates the driver only
after I changed the inf file date and version.

For my testing this is really cumbursome. Everytime I compile the driver
after minor change, I cannot reinstall the driver. I have to change inf file
also with some other version number. Is this necessary? Any workaround for my
driver testing. I didnot have problem with windows XP wherein we can do "have
disk" and overwrite the driver binary. I want to replace driver binary with
new driver binary for testing. Other information about driver can remain
same. Is there any simple way to do this?

I wish the driver installtion process be mature enough/simple enough that it
wont change just for every version of OS.
