RE: WinUsb with sleep fix for XP?
No such update exists. The win7 update works (btw your kb article number is
wrong) because winusb ships in box, there is no update for the downlevel version
installed by the coinstaller

Subject: [ntdev] WinUsb with sleep fix for XP?
What is the best way for me to provide WinUsb.sys version 2.1 (6.1.7600.16421?)
or greater for customers using our hardware with Windows XP?
We make data acquisition hardware that connects to the PC via USB and uses
WinUsb.sys as its driver. We need a sleep compatible version of WinUsb.sys so
our device can continue acquisition while the PC sleeps.
Currently, I supply our customers with an inf file and the redistributable files
WdfCoInstaller01009.dll, WUDFUpdate-01009.dll, and winusbcoinstaller2.dll from
the win7_rtm WDK 7600.16835.1. But this version of WinUsb.sys gives a timeout
error when the PC sleeps.
For Windows 7, running Windows update or applying the hotfix from knowledge base
article KB97559 results in a sleep compatible WinUsb.sys. But we also need this
update for XP and I haven't been able to find it. Any suggestions are welcome.
Thanks for your help, Wendy Tucker / Symmetric Research
