Why Do We Need WDF Coinstallers?

WinXP needs SP1 (OK, better SP2) to handle USB2.0 without problems.

So any device that's supposed to work with WinXP needs a co-installer package that includes SP2.

QED

Hagen,

If you look at http://blogs.msdn.com/iliast/archive/2007/12/13/wdf-1-7-rc1-has-been-released.aspx you'll see that we support XPSP2, but don't support XPSP1 or XP RTM. For every OS version we support only the latest SP, exactly because we didn't want to have to include the whole SP inside our coinstallers :P

Ilias,

Sorry, I left out the reference to USB, and to an even earlier time, it should have read:

"So any device that supports USB and that's supposed to run with WinXP needs a co-installer package that includes SP2."

PS: Note the absence of any WDF reference... :P

PPS: Grr - lost half of the pun this way

[Thanks for the friendly exchange of thoughts!]

Does anyone know where to get older version of WdfConInstallerxxx? I'm flailing to get a KMDF driver working in Vista. It has wdf 1.5 but I only have 1.7 to biild the driver against. I've been unable to update Vista to 1.7. Have enabled admin rights that were off by default; still to no avail.

I am Geetha from Saitechnology working in Windows Xp drivers. You had given excellent explanation for the need of WdfCoInstaler who ever uses the KMDF/UMDF framework for writing device drivers
